【摘要】 MoCl₅或WCl₆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（Ph₂PR）_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（Ph₂PEt）₂Mo（CO）₄与HgCl₂反应得到含Mo-Hg键的化合物。用（Ph₃P）₂Mo（CO）₄和（Ph₃P）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％。更多还原

【Abstract】 Phosphine substituted carbonyls of molybdenum and tungsten, （Ph₂PR）_n M（CO）_6-n （M=Mo, W; R=Me, Et, n-Pr, Ph; n=2, 3） were obtained by the reduction of MoCl₅ or WGl₆ with zinc dust in the presence of an appropriate phosphihe and carbon monoxide at room temperature and atmospheric pressure. By this method, M（CO）₅ （M=Mo, W） units were supported onto phosphine containing polymer. The compound （Ph₂PEt）₂Mo-（CO）₄ reacted with HgCl₂ to give a compound containing Mo—Hg bond.The carbonylation of methanol was primarily studied with a binary catalytic system containing （Ph₃P）₂ Me （CO）₄ and （Ph₃P）₂ Ni （CO）₂ under appropriate temperature and pressure to produce acetic acid and methyl acetate. The catalytic process gave 92％ conversion of methanol and 68％ selectivity for acetic acid and methyl acetate.更多还原
