Abstract
The five-coordinate bis(salicylaldiminato)chromium(III) complex [3,5-(t-Bu) (2)(O)C6H2CHN(2,6-i-Pr2C6H3)](2)CrCl (2) reacts with triethylaluminium in T HF at room temperature to give the air sensitive ethyl species [3,5-(t-Bu)( 2)(O)C6H2CHN(2,6-i-Pr2C6H3)](2)CrEt (3); in the presence of aluminium activ ators, 2 and 3 are moderately active ethylene polymerisation catalysts.
