Description

Main group analogues of cyclobutane-1,3-diyls attract considerable interest due to their unique reactivity and electronic properties. So far only heteronuclear examples have been isolated. Here we report the isolation and characterization of all-silicon 1,3-cyclobutandiyls as stable closed-shell singlet species from the reversible reactions of cyclotrisilene c-Si3Tip4 (Tip = 2,4,6-triisopropylphenyl) with the N-heterocyclic silylenes c [(CR2CH2)(NtBu)2]Si: (R = H or methyl) with saturated backbones. At elevated temperatures, tetrasilacyclobutenes are obtained from these equilibrium mixtures. The corresponding reaction with an unsaturated N-heterocyclic silylene c-(CH)2(NtBu)2Si: proceeds directly to the corresponding tetrasilacyclobutene without detection of the assumed 1,3-cyclobutandiyl intermediate.
