Abstract

A novel reactivity of [{Cp*Cr(CO) 3 } 2 (µ,η 1:1 ‐P 4 )] (Cp* = C 5 Me 5 ; 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 (µ,η 1:1 ‐P 4 )] (Cp‴ = C 5 H 2 t Bu 3 ; 2 ) and Cp‴ 2 ...
