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.

DMAP was found to accelerate significantly the rate of Pd(OAc)2 catalyzed Barbier type allylation of carbonyl compounds by allylbromide using SnCl2·2H2O as reducing agent. Both aldehyde as well as ketones produced excellent yields within a short reaction time in the presence of 3 mol % of Pd(OAc)2 and 12 mol % of DMAP at room temperature. Aldehydes could be allylated within 5-10 min whereas, in case of ketones, the reaction completes in 45-120 min.
