MoCl_5或WCl_6与锌粉及适当的膦配体和CO在常压常温进行反应,合成了含膦配体的羰基钼和钨的化合物(Ph_2PR)_nM(CO)_(6-n)(M=Mo,W;R=Me,Et,n-Pr,Ph;n=2,3)。用该方法也成功地将M(CO)_5(M=Mo,W)单元负载到含膦的高分子链上,化合物(Ph_2PEt)_2Mo(CO)_4与HgCl_2反应得到含Mo-Hg键的化合物。用(Ph_3P)_2Mo(CO)_4和(Ph_3P)_2Ni(CO)_2二元催化体系,在适当温度和压力下对甲醇羰基化反应进行了初步研究,得到了醋酸和醋酸甲酯。该催化过程对甲醇的转化率可达92％,对醋酸和醋酸甲酯的选择性可达68％。
The compound (Ph_2PR) _nM (CO) _ (6-n) (M = O) with molybdenum carbonyl and tungsten containing phosphine ligand was synthesized by reaction of MoCl_5 or WCl_6 with zinc powder and the appropriate phosphine ligand and CO at normal temperature and pressure. Mo, W; R = Me, Et, n-Pr, Ph; n = 2,3). With this method, M (CO) _5 (M = Mo, W) units were successfully loaded onto the polymer chains containing phosphine. The reaction of compound (Ph_2PEt) _2Mo (CO) _4 with HgCl_2 resulted in the compound containing Mo-Hg bond . The carbonylation of methanol was studied under the appropriate temperature and pressure with (Ph_3P) _2Mo (CO) _4 and (Ph_3P) _2Ni (CO) _2 binary catalysts. Acetic acid and methyl acetate were obtained. The catalytic conversion of methanol up to 92%, the selectivity of acetic acid and methyl acetate up to 68%.
