Mixed allylbutyltin halides (CH2=CHCH2)SnBu3-nCln (n=0-3) have been prepared, and characterized by carbon-13 NMR spectroscopy.Their ability to bring about allylstannylation of ketones and aldehydes, to form organostannoxy compounds, Bu3-nSnClnOC(R')(R'')CH2CH=CH2, has been shown to increase on increasing the value of n, that is on increasing the acceptor ability of the tin centre.

An eco-friendly synthesis of cyclic carbonates through a Lewis acid catalyzed cyclization of tert-butyl carbonates is described. These cyclic carbonates are precursors of 1,2- and 1,3-diols, and the developed method was applied to a short synthesis of a diarylheptanoid, (3S,5S)-alpinikatin.
SnCl2·2H2O-mediated Barbier-type allylation: A comparative evaluation of the catalytic performance of CuI and Pd(OAc) 2

A systematic investigation has been carried out for the allylation of carbonyl compounds under SnCl2·2H2O-mediated Barbier-type conditions, using CuI and Pd(OAc)2 as catalysts. Ketones, which are not reactive under the influence of CuI, however, could be activated by using Pd(OAc)2 as a catalyst.
