Sila-heterocycles, ditrisyldibromodisiladioxetane (trisyl = C(SiMe3)3) 2 and ditrisyldibromodithiadisiletane 3, were generated at a low temperature from the reaction of trisylbromosilylenoid 1 with heterocumulenes such as phenyl isocyanate and phenyl isothiocyanate. The 29Si-NMRs of sila-heterocycles were then investigated. The reaction of cyclic compounds 2 and 3 with MeOH gave dimethoxy(trisyl)silanol 4 and dimethoxy(trisyl)silanethiol 5, respectively, through ring cleavage and substitution reactions. This work is the first investigation of the reactivity of silylenoid with heterocumulenes.
