The oxidative addition reaction of silylenes with proton-containing molecules is an effective method for synthesis of hydrosilicon species. Herein, amidinatoborylaminosilylenes (L)[(1,5-C8H14)B(R)N]Si [L=PhC(NtBu)2; R=2,4,6-Me3C6H2 (1), 2,6-iPr2C6H3 (2), 1-C10H15 (3)] were employed, each of which reacted with 1-(diphenylmethyl)-3-hydroxyazetidine to produce the derived alkoxyl hydrosilicon compounds (L)[(1,5-C8H14)B(R)N]Si(H)[O-cyclo-CH(CH2)2N(CHPh2)] (4~6), and with mercaptans as 2-naphthalenethiol, 4-fluorothiophenol, 2-chlorobenzenethiol to yield thiol hydrosilicon compounds (L)- [(1,5-C8H14)B(R)N]Si(H)(SR') (7~14). Silylene 1 reacted with diphenylamine to give (L)[(1,5-C8H14)B(2,4,6-Me3C6H2)N]- Si(H)(NPh2) (15). Compounds 4~15 have been characterized by NMR spectra and elemental analysis, of which 5, 7 and 11 were further confirmed by X-ray crystallography. Compounds 4~15 are the hydrosilicon species with novel structures and compositions, all of which are bonded by four different groups, being generated by the oxidative addition reaction via the silylene Si: center toward the respective O—H, S—H, and N—H bonds of the proton-containing molecules, where a mode of a charge reversal of the proton into the hydride group at the Si center is realized.

Key words: silylene, proton-containing molecule, oxidative addition reaction, hydrosilicon compound
