  摘要：

  研究了作为乙烯基化合物聚合催化剂的烷基硼衍生物，如二烷基硼酰氯、二烷基硼酸、二烷基硼酯和二烷基硼氧化物。虽然二烷基硼酸是一种很好的催化剂，但要纯粹分离出这种催化剂却相当困难，因此本文只作了简要介绍。当然，有些二烷基硼酸可以在适当的条件下纯粹分离出来。本文研究了苯乙烯在这些催化剂作用下的聚合速率、转化率与固有粘度之间的关系以及氧对聚合速率的影响。当 O2/催化剂的摩尔比为 0.22 时，某些单体与二烷基硼酸酯的聚合速率最大。

• Selective preparation of borinic esters from Grignard reagents and selected trialkoxyboranes

  The reaction of trialkoxyboranes with ethylmagnesium bromide was investigated for the selective alkylation to the symmetrical borinic esters, R2BOR'. Triisopropoxyborane was found to react cleanly with 2 equiv of the Gringnard reagent to form diethylisopropoxyborane at -40-degrees-C. The selectivity of this reaction is largely controlled by the stability of the bromomagnesium diethyldiisopropoxyborate, MgBr[Et2B(O(i)Pr)2]. Triisopropoxyborane was found to be the most selective borane examined, yielding symmetrical borinic esters for primary and aryl derivatives with high selectivities. Secondary alkyl groups showed lower selectivities. This reaction has been developed into a general procedure for preparation of diorganyl-alkoxyboranes from readily available organomagnesium reagents, especially for those containing organic groups which are not accessible via hydroboration.

  Such alkylboron derivatives as dialkylboron chloride, dialkylborinic acid, dialkylboronous ester, and dialkylboron oxide as the catalysts for the polymerization of vinyl compounds were studied. Although dialkylborinic acid was a good catalyst, it was pretty difficult to isolate it purely, therefore, only a brief description was made in this paper. Of course, some dialkylborinic acids can be isolated purely under suitable conditions. In regard to this, further investigation will be performed.The polymerization rates of styrene with these catalysts, the relation between the conversion and the intrinsic viscosity, and the influence of oxygen on the polymerization rate were studied. The polymerization rate of some monomers with dialkylboronous ester is maximum when O2/catalyst in mole ratio is 0.22.
