Description
A substrate for nickel-catalyzed cross-coupling with benzonitriles. Pyrazole syntheses by 1,3-Dipolar cycloaddition of diazo compounds to acetylenes.Ethynyltrimethylsilane was used in:• microwave-assisted, one-pot, three-step Sonogashira cross-coupling-desilylation-cycloaddition reaction for the preparation of 1,4-disubstituted 1,2,3-triazoles• synthesis of poly(ethynyltrimethylsilane) containing Pd (II) coordination sites• pyrazole synthesis via 1,3-dipolar cycloaddition of diazo compounds to acetylenes
