reaction between various chromiumcarbenecomplexes [Cr(CO)5C(X)(C6H4Y)}](X = OMe or NC4H8; Y =p-OMe, p-Cl, or H) and ER3H (E = Ge, R = Et or Ph; E = Sn, R = Bun or Ph) in the presence of pyridine in hexane solution have been measured by i.r. spectrophotometry under pseudo-first-order conditions in the range 260–330 K. The results are compared with those for analogous silicon hydrides (E = Si, R = Et or
