中文摘要:
      研究了烷基二苯基膦-铑配合物RhCl(CO0(n-C8H17PPh2)2(1)和RhCl(Co)(n-C12H25PPh2)2(2)对1-辛烯氢甲酰化反应的催化性能。结果表明,配合物1比2具有更高的催化活性,而配合物2对生成正构醛的选择性更好;当催化剂浓度或膦/铑比增加时,配合物2催化成正构醛的选择性呈下降趋势,显示出与以PPh3为配体时的不同的性能。
英文摘要:
      The catalytic performance of long chain alkyl diphenylphosphine rhodium complexes, \{RhCl\|\}(CO)( n C\-8H 17 PPh\-2)\-2(1) and RhCl(CO)( n C\-\{12\}H 25 PPh\-2)\-2(2), in hydroformylation of 1 octene were studied. Both 1 and 2 show good performance for hydroformylation of 1 octene, however, complex 1 exhibits higher activity, and complex 2 is more selective to the form ation of linear aldehyde. The increase of catalyst concentration is favorable to the conversion of 1 octene to aldehyde, but results in lower regioselectivity for linear aldehyde. In contrast to the performance of PPh\-3, the increase of molar ratio of phosphine to rhodium causes the decrease of regioselectivity for linear aldehyde when using 2 as the catalyst precursor.
