Reactions of 4-diphenylphosphino benzoic acid with organotin oxides and -oxy-hydroxide

Abstract

The reactions of p-diphenylphosphinobenzoic acid (LCOOH) with various organotin precursors have been carried out. Accordingly, the reaction of [n-BuSn(O)(OH] n with LCOOH afforded the hexameric compound, [n-BuSn(O)O 2 CC 6 H 4p-PPh 2 ] 6 (1). On the other hand, the reaction of LCOOH with [n-Bu 2 SnO] n gave the tetrameric compound [{n-Bu 2 SnO 2 CC 6 H 4p-PPh 2 } 2 O] 2 (2). The 1-D coordination polymers [R 3 SnO 2 CC 6 H 4p-P(O)Ph 2 ] n , [R = n-Bu (3), R = Ph (4)] were prepared in the reaction of [n-Bu 3 Sn] 2 O or [Ph 3 Sn] 2 O with LCOOH. The compounds 1-4 were structurally characterized by multinuclear NMR spectroscopic and single crystal X-ray diffraction studies.
