Highly Efficient Recyclable Sol Gel Polymer Catalyzed One Pot Difunctionalization of Alkynes.

ABSTRACT: Amino-bridged gel polymer P1 was discovered to catalyze alkyne halo-functionalization in excellent yields, regioselectivity, functional group compatibility, and recyclability. We have observed that both aromatic and aliphatic alkynes can be converted to ?,?-dihalogenated ketones in the presence of polymer P1 under metal-free conditions at room temperature within a short reaction time.

Amino-bridged gel polymer <b>P1</b> was discovered to catalyze alkyne halo-functionalization in excellent yields, regioselectivity, functional group compatibility, and recyclability. We have observed that both aromatic and aliphatic alkynes can be converted to α,α-dihalogenated ketones in the presence of polymer <b>P1</b> under metal-free conditions at room temperature within a short reaction time. ...[more]
