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

Abstract

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 2C –C 6H 4–p-PPh 2] 6 (1). On the other hand, the reaction of LCOOH with [n-Bu2SnO]n gave the tetrameric compound [{ n-Bu 2SnO 2C –C 6H 4–p-PPh2}2O]2 (2). The 1-D coordination polymers [R 3SnO 2C –C 6H 4–p- P(O)Ph 2] n, [R = n-Bu (3), R = Ph (4)] were prepared in the reaction of [n-Bu3Sn]2O or [Ph3Sn]2O with LCOOH. The compounds 1–4 were structurally characterized by multinuclear NMR spectroscopic and single crystal X-ray diffraction studies. Graphical Abstract: SYNOPSIS The reactions of p-diphenylphosphinobenzoic acid with various organotin precursors have been shown to afford hexameric compound 1, tetrameric compound 2 and 1-D polymeric compounds 3 and 4. The compounds 1–4 were structurally characterized by multinuclear NMR spectroscopic and single crystal X-ray diffraction methods. [Figure not available: see fulltext.].
