## Reactions of 2-aryl-l,3-dithiolane-S-oxides 1 with MeMgI in refluxing benzene-ether furnish a useful procedure for introducing the isopropenyl group. The reaction may proceed via a fragmentation-coupling process leading to the alkylative olefination product.
l-Phenylphosphol-2-en-1-oxide la reacts with aryl iodides in the presence of ammonium formate and a catalytic amount of Pd(OAc)2 to give 3-aryl-1 -phenylphospholane-1-oxides 3, whereas 4-aryl-1 -phenylphosphol-2-en-1oxides 4 are obtained from l-phenylphosphol-3-en-l-oxide 2a under modified Heck reac
