1.The reactions of silylcyclopropanones with compounds containing a mobile hydrogen atom and also with alkoxy, dialkylamino, and dialkoxyphosphinooxy derivatives of Group IVB elements give adducts at the carbonyl group of the cyclopropanone, and, when heated, these undergo isomerization with opening of the three-membered ring exclusively at the C1-C2 bond and with the formation of β-heteroelement-substituted propionic derivatives. 2.Acetic acid and bis(trifluoroacetic) anhydride in reaction with (trimethylsilyl)cyclopropanone form relatively stable products of addition at the carbonyl group. 3.Bromine and iodotrimethylsilane react with silylcyclopropanones with breakage of the C2-C3 bond of the cyclopropanone ring and give the corresponding O- and C-isomeric derivatives of α-silylated ketones containing halogen atoms in the molecule. 4.The reactions of silyl- and germyl-cyclopropanones with diazomethane and with azido-silanes and -germanes can provide a method of synthesis of heteroelement-substituted (Si, Ge) cyclobutanones and β-lactams.
