Abstract The cleavage of element-element bonds in ligands of the type R 2 EER′ 2 and R 2 EE′R′ (R, R′ = CH 3 , CF 3 ; E = P, As; E′ = S, Se, Te) coordinated to M(CO) 5 -fragments (M = Cr, Mo) by Me 3 SnH (Me = CH 3 ) has been studied in some detail by NMR spectroscopic measurements ( 1 H, 19 F). In comparison with the analogous reactions of the free ligands, the rate of reaction is considerably reduced, wheras the cleavage direction is generally retained. Possible reaction intermediates have been synthesized by independent routes and tested under comparable conditions.
