A new synthesis of allyl sulfoxides via nucleophilic addition of sulfinyl carbanions to group 6 Fischer carbene complexes.
[reaction: see text] A novel synthesis of allyl sulfoxides has been developed. Primary alpha-lithiosulfinyl carbanions react with group 6 Fischer carbene complexes to give allyl sulfoxides as products. The Fischer carbene complex experiments involve a 1,2-addition of two molecules of sulfinyl carbanion to give an intermediate that, after a beta-elimination, furnishes the mentioned product.
