Abstract

(Z)-1-Trimethylsilyl-1-alkenes easily prepared by the hydroboration of the corresponding 1- trimethylsilyl-1-alkynes followed by protonolysis with acetic acid, readily react with dibromoborane-methyl sulfide complex in dichloromethane for 6 h. The resulting solution is then treated with 1, 3-propane diol in a 1: 1 mixture of dichloromethane and n-pentane at 0° C for half an hour to provide the corresponding gem-dimetalloalkanes containing boron ...
