摘要：

The new borate [CPh3](+)[CN{B(C6F5)(3)}(2)](-) and the anionic isocyanoborate complex [Ni{CNB(C6F5)(3)}(4)](2-) are readily accessible in one-pot reactions and act as a highly efficient activators for metallocene polymerisation catalysts; turnover numbers of up to 53 000 s(-1) appear to be the highest reported so far for ethene polymerisation catalysts.
