Organotin Selenocarboxylates: Synthesis and Some Reactions

Abstract
A series of di- 3 and triorganotin esters 2 of aromatic selenocarboxylic acid were synthesized and characterized. The organotin esters 2 and 3 are stable thermally, but labile towards moisture and oxygen. They readily reacted with benzyl bromide in the presence of aluminum chloride to afford benzyl selenocarboxylates 4 in moderate yields. The reaction of triphenyltin selenocarboxylates with phenylselenenyl bromide led to aryl phenyl diselenides 5 in good yields.
