A new route to (Z)-beta-silylacryloylsilanes 10 and the improved conditions for the [3 + 2] annulation using 10 and alkyl methyl ketone enolates are reported. Also, details of investigations defining a reaction course of the [3 + 2] annulation using beta-phenylthio- and beta-trimethylsilyl-acryloylsilanes 1 (X = SPh, SiMe(3)) and alkyl methyl ketone enolates are described.
