Abstract

The functionalized (fluoroaryl)borate salts Ph3C+B(C6F4TBS)4- and Ph3C+B(C6F4TBS)4- and (TBS - tBuMe2Si; TIPS = iPr3Si) are prepared in three steps from 1,4-HC6F4Br. Reaction with zirconocene dimethyls yields crystalline, thermally stable, soluble L2ZrCH3+B(C6F4SiR3)4- and L2-ZrH+(C6F4SiR3)4- salts (L = η5-C5H5; η5-1,2-Me2C5H3; L+ = η5-Me5C5) which function as highly active ethylene polymerization catalysts.
