INTERMEDIATES AND PRODUCTS OF THE REACTION OF MOCL5 WITH ETHANOL - CRYSTAL-STRUCTURES OF [MOOCL3(ETOH)] AND H[MOOCL4]CENTER-DOT-2ETOH

An intermediate in the ethanolysis reactions of MoCl5, [MoOCl5(EtOH)] 2, has been isolated after the reaction of MoCl5 with 2 equivalents of EtOH and its crystal structure was determined. Treatment of MoCl5 wit h 2.5 equivalents of EtOH and subsequent cooling as well as the reacti on of [Cl2OMo(mu-OEt)(2)(mu-HOEt)MoOCl2] 1 with HCl(g) yield a product which has been identified as H[MoOCl4]. 2EtOH 3 by X-ray crystallogra phy. The mechanisms leading to 1-3 are discussed. The reactions of 2 w ith donors have been investigated and [Cl2OMo-(mu-OPr)(2)(mu-HOPr)MoOC l2] 4 was obtained as a first derivative of 1 after the reaction of Mo Cl5 with PrOH.
