Preparation method of alkyl tin compound or benzyl tin compound

The invention discloses a preparation method of an alkyl tin compound or a benzyl tin compound. N-tosylhydrazones, tri-n-butyltin hydride and alkali react in an organic solvent to obtain the alkyl tin compound or the benzyl tin compound. The addition of a phase transfer catalyst can effectively promote the reaction. According to the method disclosed by the invention, it is first time that the alkyl tin compound or the benzyl tin compound is directly obtained under the mild condition from N-tosylhydrazones without transition metal, the reaction efficiency is high, the reaction cost is low, and the method has good tolerance and universality on functional groups and can be widely used for preparing the alkyl tin compound or the benzyl tin compound.

Preparation of benzylstannanes by zinc-mediated coupling of benzyl bromides with organotin derivatives. Physicochemical characterization and crystal structures

Benzyltrialkyl- (1-13) and benzyltriphenylstannanes (16-22) have been easily prepared in a one-pot synthesis via coupling reaction of benzyl bromide derivatives (C6H5CH2Br and XYC6H3CH2Br, X = H, Y = o-, m-, p-CH3, o-, m-, p-F, o-, m-Cl, and p-Br; X = o-F, Y = p-Br) with R3SnCl compounds (R = Et, Pr, Bu, and Ph) in THF/H2O (NH4Cl) medium mediated by zinc powder. Such coupling also occurs with (Bu3Sn)2O. Dibenzyldibutylstannane (15) is prepared by reaction of benzyl bromide with Bu2SnCl2 or (Bu2SnCl)2O, and (2-naphthylmethyl)tributylstannane (14) by reaction of 2-(bromomethyl)naphthalene with Bu3SnCl. 13C-and 119Sn-NMR data are reported for all compounds, and M?ssbauer data for benzyltributylstannanes 10 and 11 and benzyltriphenylstannanes 16-18 and 20-22. The crystal structures of Ph3SnBn, with Bn = o- (17) and m-ClC6H4CH2 (18) and o- (20) and m-FC6H4-CH2 (21) have been determined.
