E-alkenyl Grignardreagents selectively and in almost quantitative yields. The regiochemistry of this hydromagnesation reaction is high for alkylarylacetylenes and silylacetylenes giving E-ArC(MgBr)CHR from alkylarylacetylenes, E-ArC(MgBr)CH(SiMe3) from arylsilylacetylenes, and ECHRC(MgBr)(SiMe3) from alkylsilylacetylenes, respectively. Thanks to the high reactivity of the Grignardreagent, the present
