Aryl derivatives of antimony (V) of the general formula Ar4SbX [X= Hlg, NO3, SCN, OSO2R, OC (O) R] can be prepared by the reaction of pentaarylantimony and a symmetrical antimony (V) derivative Ar3SbX2 in an yield of up to 98%[134]. Analogos reactions of pentaarylantimony with diaroxytriphenyl derivatives of antimony are unknown. We have found a new method for preparing tetraphenylantimony aroxides by the reaction of ...
