Abstract
The reaction of cyclopropylcarbinyltrialkylstannanes (CPCSnR3) 1a (R=Me) and 1b (R=Bu) with sulfur dioxide in chloroform or methanol yields the homoallylic tin sulphinates 2a and 2b respectively. The reaction of 1a with iodine in chloroform yields predominantly 4-iodo-1-butene (3) and trimethyltin iodide while in methanol the corresponding reaction yields CPCSnMe2I (4) and methyl iodide.
