Synthesis of the Hydrosilicon Species via Oxidative Addition of Silylene toward the Proton-Containing Molecules
The oxidative addition reaction of silylenes with proton-containing molecules is an effective method for synthesis of hydrosilicon species.Herein,amidinatoborylaminosilylenes(L)[(l,5-C8H14)B(R)N]Si[L=PhC(NtBu)2;R=2,4,6-Me3C6H2(1),2,6-iPr2C6H3(2),1-C10H1s(3)]were employed,each of which reacted with l-(diphenylmethyl)-3-hydroxyazetidine to produce the derived alkoxyl hydrosilicon compounds(L)[(l,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)-[(l,5-C8H14)B(R)N]Si(H)(SR')(7～14).Silylene 1 reacted with diphenylamine to give(L)[(l,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 si-lylene 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.
