An efficient stannylation process with N-tosylhydrazones or directly with carbonyl compounds has been developed. A series of functionalized benzyl- and alkyltributylstannanes can be synthesized in moderate to good yields under transition-metal-free conditions. Tandem transformations involving stannylation/Stille cross-coupling reaction have been carried out without purification of the benzyltributylstannane intermediates to afford a series of diarylmethane derivatives.

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.
