The search for a stable, inexpensive, and easy-to-handle activator toward the catalyst precursor [Co(tpy)Br₂] in the hydrosilylation of olefins with hydrosilane revealed that K₂CO₃ is an effective activator. This inorganic salt is available on substrates with some functional groups and can be readily removed by simple filtration or centrifugation after the reaction. After examining and comparing the activator abilities of various salts, it was proposed that low MX lattice energy, high X-nucleophilicity, and a strong Si–X bond are necessary for an inorganic salt (MX) to be an excellent activator.

二溴联三联吡啶配合物氢化硅烷化预催化剂无机活化剂的研究

在烯烃与氢硅烷氢化硅烷化反应中寻找稳定、廉价且易于处理的催化剂前体 [Co(tpy)Br ₂ ] 活化剂表明，K ₂ CO ₃是一种有效的活化剂。这种无机盐可在具有某些官能团的底物上使用，并且可以在反应后通过简单的过滤或离心轻松去除。在检查和比较各种盐的活化剂能力后，提出低 MX 晶格能、高 X-亲核性和强 Si-X 键是无机盐 (MX) 成为优异活化剂所必需的。
