7-(tert-Butyl-diphenyl-sil-yloxy)-2,2-dimethyl-1-benzofuran-3(2H)-one.

ABSTRACT: The title compound, C(26)H(28)O(3)Si, is an allylic oxidation product of the tert-but-yl(2,2-dimethyl-2,3-dihydro-benzo-furan-7-yl-oxy)diphenyl-silane with N-bromo-succinimide and 2,2'-azobis-isobutyronitrile. The nine-atom bicyclic system is almost planar, with an r.m.s deviation of 0.0123?(2)?Å and a maximum deviation of 0.031?(2)?Å for the O atom. In the crystal, the mol-ecules pile up along the b axis but the strongest inter-molecular contacts are the ?-? stacking inter-actions between the benzene rings along the c axis [centroid-centroid distance = 3.655?(3)?Å].

4-[(tert-Butyl-diphenyl-sil-yloxy)meth-yl]pyridazin-3(2H)-one.

Project description:In the title compound, C21H24N2O2Si, the carbonyl group of the heterocyclic ring and the O atom of the silyl ether group are placed toward opposite sides and the tert-butyl and pyridazinone moieties are anti-oriented across the Si-O bond [torsion angle = -168.44?(19)°]. In the crystal, mol-ecules are assembled into inversion dimers through co-operative N-H?O hydrogen bonds between the NH groups and O atoms of the pyridazinone rings of neighbouring mol-ecules. The dimers are linked by ?-? inter-actions involving adjacent pyridazinone rings [centroid-centroid distance = 3.8095?(19)?Å], generating ladder-like chains along the b-axis direction. The chains are further linked into a two-dimensional network parallel to the ab plane through weak C-H?? inter-actions.

5-[(tert-Butyl-diphenyl-sil-yloxy)meth-yl]pyridazin-3(2H)-one.

Project description:In the title compound, C21H24N2O2Si, a new pyridazin-3(2H)-one derivative, the carbonyl group of the heterocyclic ring and the O atom of the silyl ether are located on the same side of the pyridazinone ring and the C-C-O-Si torsion angle is -140.69?(17)°. In the crystal, mol-ecules are linked by pairs of strong N-H?O hydrogen bonds into centrosymmetric dimers with graph-set notation R 2 (2)(8). Weak C-H?? inter-actions are also observed.

1,1'-Bis(tert-butyl-dimethyl-sil-yl)ferrocene.

Project description:The asymmetric unit of the title compound, [Fe(C11H19Si)2], consists of one half of a ferrocene derivative. The Fe(II) atom lies on a twofold rotation axis, giving an eclipsed conformation for the cyclo-penta-dienyl ligands. No significant inter-molecular inter-actions are observed in the crystal structure.

4-[(tert-Butyl-dimethyl-sil-yl)-oxy]-6-meth-oxy-7-methyl-5-(oxiran-2-ylmeth-yl)-2-benzofuran-3(1H)-one.

Project description:The title compound, C(19)H(28)O(5)Si, was obtained in the reaction of 1,3-dihydro-4-[(tert-butyl-dimethyl-sil-yl)-oxy]-6-meth-oxy-7-methyl-3-oxo-5-(prop-2-en-yl)isobenzofuran with meta-chloro-perbenzoic acid. This reaction is one of the stages of the total synthesis of mycophenolic acid, which we attempted to modify. The title compound forms crystals with only weak inter-molecular inter-actions. The strongest stacking inter-action is found between the benzene and furan rings of inversion-related mol-ecules with a distance of 3.8773 (13) Å between the ring centroids.

1,1,3,3-Tetra-tert-butyl-2,2-diisopropyl-4,4-diphenyl-cyclo-tetra-silane.

Project description:The molecule in the structure of the title compound, C34H60Si4, lies on a twofold rotation axis that passes through the two Si atoms, resulting in a planar cyclo-tetra-silane ring. The dihedral angle between the cyclo-tetra-silane ring and the phenyl ring is 68.20?(5)°. The Si-Si bonds [2.4404?(8) and 2.4576?(8)?Å] are longer than a standard Si-Si bond (2.34?Å) and the C-Si-C bond angle [97.07?(14)°] of the phenyl-substituted Si atom is smaller than the tetra-hedral bond angle (109.5°). These long bonds and small bond angle are favorable for reducing the steric hindrance among the bulky substituents.

Crystal structure of (2,2'-bi-pyridine-?2N,N')-trans-bis-(tert-butyl-dimethyl-sil-yloxy)-cis-dioxidomolybdenum(VI).

Project description:In the title compound, [( t BuSiMe2O)2MoO2(2,2'-bi-pyridine)] or [Mo(C6H15OSi)2O2(C10H8N2)], the MoVI atom has a distorted octa-hedral environment with the sil-oxy substituents occupying the trans positions. The complex contains a rare (R3SiO)2MO2 (M = Mo, W) structural motif and was formed in a reaction between sodium molybdate and tert-butyl-dimethyl-silyl chloride in the presence of 2,2-bi-pyridine. In the crystal, neighbouring mol-ecules are linked by C-H?O=Mo hydrogen bonds, forming chains propagating along the a-axis direction.

(±)-(4aR,5R,8S,8aR)-8-(tert-Butyl-dimethyl-sil-yloxy)-2,5,8a-trimethyl-4a,5,8,8a-tetra-hydro-naphthalene-1,4-dione.

Project description:In the title compound, C19H30O3Si, both rings adopt a half-boat conformation. Overall, the mol-ecule approximates a U-shape as the cyclo-2-ene-1,4-dione and butyl-dimethyl-sil-yloxy substituents lie to the same side of the central cyclo-hexene ring; the methyl substituent lies to the other side of the mol-ecule. In the crystal, linear supra-molecular chains along the b axis are sustained by C-H?O inter-actions.

Project description:The title compound, C(7)H(14)N(3) (+)·C(25)H(40)N(3)O(4)Si(2) (-)·CH(3)CN, was obtained by the reaction of 2-nitro-1,3-di(pyridin-2-yl)-1,3-di(tert-butyl-dimethyl-sil-yloxy)propane with 1,3,4,6,7,8-hexa-hydro-2H-pyrimido[1,2-a]pyrimidine. Two hydrogen bonds stabilize the Lewis acid/base pair of the nitro-nate and the guanidinium moiety with N⋯O distances of 2.772 (3) and 2.732 (3) Å. Both hydrogen atoms are more closely bound to the guanidinium [N-H distances of 0.83 (3) and 0.93 (3) Å] than to the nitro-nate moiety. The nitro-nate is double-bonded to the respective carbon with an N=C bond length of 1.316 (3) Å.
