摘要： New silylsubstituted 1,2-alkynes of the general formula 1 and a new way of synthesis of new and already known silylsubstituted 1,2-alkynes of the general formula 1. The unknown silylsubstituted 1,2-alkynes of general formula 1, in which R1 stands for trialkoxysilyl group, dimethyl(trimethylsiloxy)silyl group, phenyldimethylsilyl group, methylbis(trimethylsiloxy)silyl group; R2 stands for alkyl, trialkylsilyl group with all alkyl substituents the same, 1-trimethylsiloxycycloalkyl group, cycloalkyl group, tertbutyl group, 1-trimethylsiloxyalkyl group, tertbutyldimethylsilyl group or 1-alkoxyalkyl group. The subject matter of the invention is a new way of synthesis of new and already known silylsubstituted 1,2-alkynes of general formula 1, in which R1 and R2 specified above, in which an alkene of general formula 2, with R1 specified above is subjected to silylative coupling with a terminal alkynes of the general formula 3, with R2 specified above, in the presence of a catalyst.
