Transition-metal Derivatives of Silicon, Germanium, Tin, and Lead

Transition-metal Derivatives of Silicon, Germanium, Tin, and Lead.—The silylation of (C5H5)TiCl2 with SiHaK yields the olive-green, benzene-soluble 

The reaction of H3GeBr with NaRe(CO)s affords H3GeRe(CO)s, accompanied by a very low yield of a second product, tentatively identified as GeH2[Re(CO)g]2. ReSnL4Cl4,H20 (L = thiourea) is prepared by allowing 

HRe04 in 3N hydrochloric acid to react with thiourea and tin(ii) chloride in 10N-HC1.i°24
