Sodium selenocarboxylates were found to react with organoarsanyl chlorides Ph3-(n)AsCl(n) 1-3 (n = 1, 2, 3) to give the corresponding Se-organoarsanyl esters RCOSeAsPh2 (5), (RCOSe)2AsPh (6) and (RCOSe)3As (7) in good yields. The reaction of Se-diphenylarsanyl 4-methylbenzenecarboselenoate 5g with phenylselenenyl bromide and phenyltellurenyl iodide afforded the corresponding Se-phenyl-selenenyl 13 and Se-phenyltellurenyl esters 14 in moderate yields, while the reaction with sodium phenoxide gave sodium 4- methylbenzenecarboselenoate (4g), phenyl 4-methylbenzoate (11) and phenoxydiphenylarsine (12), indicating the attack of phenoxy anion to both the carbonyl carbon and arsenic atoms.
