摘要：

The novel optically active phosphine, bis(8-phenyloctyl) (Menth = 1R, 3R, 4S (-) methly) phosphine, (M sized and sulfonated under mild conditions to yield the corresponding sulfonated phenyl) octyl)(Menth) phosphine. The water soluble phosphine is used to generate an the hydroformylation of styrene. The catalyst shows high catalytic activity, but virtually no optical induction. Normal to branch ratios for the hydroformylation of styrene are in the range 0.35 to 0.5. The catalytic data with TPPTS is given for comparison. TPPTS yields catalysts that are less active under two phase reaction conditions and slightly less selective for formation of 2-phenylpropanal.
