Nakamura, Shinji Uchiyama, Masanobu Ohwada, Tomohiko Chemoselective Silylzincation of Functionalized Terminal Alkynes Using Dianion-Type Zincate (SiBNOL-Zn-ate):  Regiocontrolled Synthesis of Vinylsilanes A regio- and chemoselective silylzincation reaction of various functionalized alkynes was developed using a newly designed dianion-type zincate. Silylzincation of terminal alkynes, followed by electrophilic trapping, proved to be a powerful tool for the one-pot, regiocontrolled generation of trisubstituted functionalized alkenes. The functionalized vinylzincate intermediate also undergoes copper- and palladium-catalyzed C−C bond-forming reactions in high yields and with high regio- and chemoselectivities. terminal alkynes;chemoselective silylzincation reaction;Chemoselective Silylzincation;functionalized vinylzincate;trisubstituted functionalized alkenes;regiocontrolled generation;Functionalized Terminal Alkynes;functionalized alkynes 2004-09-15
