对氢化硅烷化反应所用铂催化剂已进行了大量的研究,但以氯铂酸(钠)的冠醚络合物作为氢化硅烷化反应的催化剂至今未见报导。冠醚用于铂系金属的络合多是以含氯,含硫的环状化合物为配体。氯铂酸(钠)冠醚络合物的研究旨在寻求室温惰性、高温有良好活性和能反复使用的新型氢化硅烷化反应催化剂。本文报导了氯铂酸及其钠盐和18-冠-9及1,7,10,16-四氧-4,13,二氮环十八烷(简称([2,2])的冠醚络合物的合成,物性及其对不饱和化合物的硅氢加成反应的催化活性和选
A great deal of research has been done on platinum catalysts for hydrosilylation, but no crown ether complex of sodium chloroplatinate has been reported as a hydrosilylation catalyst. Crown ether for platinum complex metal complexes are more chlorine, sulfur compounds containing the ring as a ligand. The research of chloroplatinic acid (sodium) crown ether complex aims to seek a new type of hydrosilylation reaction catalyst which is inert at room temperature, has good activity at high temperature and can be reused. This paper reports the effects of chloroplatinic acid and its sodium salts and crown ethers of 18-crown-9 and 1,7,10,16-tetraoxy-4,13-diazacyclooctadecane ([2,2]) Synthesis, physical properties of complexes and their catalytic activity and selectivity to hydrosilylation reactions of unsaturated compounds
