Abstract

A novel reactivity of [{Cp*Cr(CO)(3)}(2)(mu,eta(1:1)-P-4)] (Cp*=C5Me5; 1) is reported, which utilizes the selective cleavage of the two P-Cr bonds and subsequently initiates a substituent exchange yielding P-4 butterfly compounds. By means of NMR and IR spectroscopy studies, the successful implementation of 1 to obtain [{Cp ''' Fe(CO)(2)}(2)(mu,eta(1:1)-P-4)] (Cp '''=(C5H2Bu3)-Bu-t; 2) and Cp ''' ...
