Abstract
Bis(diphenylphosphino)methane, dpm, reacts with hexacarbonylmolybdenum to give Mo(CO)4 dpm and subsequently trans-Mo(CO)2(dpm)2. Oxidation of the tetracarbonyl derivative with iodine yielded Mo(CO)3(dpm)I2; reaction of this complex with further dpm gave Mo(CO)2(dpm)2I2. As with the corresponding tungsten system there are two isomers of Mo(CO)2(dpm)2I2 and three isomeric forms of Mo(CO)2(dpm)2I2 which can be obtained by this method of synthesis, all of which have been isolated and characterized individually. trans- Mo(CO)2(dpm)2 reacts with iodine to give a fourth isomeric form of the iododicarbonyl complex, trans- [Mo(CO)2(dpm)2]I2 which is a new type of halocarbonyl complex of molybdenum(11).https://doi.org/10.1071/CH9700223
