Abstract

A series of 2-, 3-or 4-trifluoromethyl substituted triarylphosphines and their oxide, chalcogenide and Fe (CO) 4 derivatives have been prepared and characterised spectroscopically and crystallographically. Electronic effects of CF3 substitution are cumulative and felt equally in the 2, 3 or 4 position. Substitution in the 2 position substantially hinders the complexing ability for steric reasons. Correlated P–C rotation in ...
