The diverse reactivity of NOBF towards silylene, disilene, germylene and stannylene
The reactivity of NOBF 4 towards silylene, disilene, germylene, stannylenes has been described. Smooth syntheses of compounds of composition [PhC(N t Bu) 2 E(= O → BF 3 )N(SiMe 3 ) 2 , E = Si ( 3 ) and Ge ( 4 )] were accomplished from the corresponding tetrylenes. An unusual heterocycle ( 10 ) featu...

) 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 (

Herein, we report an unprecedented reactivity pattern of NOBF

towards the low-valent group 14 compounds, starting from oxygenation to a fluorinating agent. |
