The reactivity of NOBF towards silylene, disilene, germylene, stannylenes has been described. Smooth syntheses of compounds of composition [PhC(NtBu)E(= O → BF)N(SiMe), E = Si (3) and Ge (4)] were accomplished from the corresponding tetrylenes. An unusual heterocycle (10) featuring B, Sn, N, P, and O atoms was obtained from the reaction with a stannylene, while a 1,2-vicinal anti addition of fluoride was observed with a disilene (12).
