Nickel-catalysed alkylative alkenation of orthothioesters with grignard reagents; a convenient procedure for introducing the isopropenyl group. Synthesis of substituted 1,3-(bis-trimethylsilyl)propenes
Abstract
Nickel-catalysed coupling of orthothioesters with MeMgl furnishes a general method for introducing the Isopropenyl group; the application of this reaction to the synthesis of 1,3-(bis-trimethylsilyl)propenes is presented.
