The original objective of the research was to compare the reactions of MoOCl3 [(C6H5)3P]2 and ReOCl3[(C6H5)3P]2. In particular a study of the molybdenum-oxygen moiety and the replacement of the chloride ion trans to the oxygen with an alkoxy group. These reactions were to be conducted in a sealed tube or unreactive solvent. In an attempt to simplify the synthesis of MoOCl3 [(C6H5)3P]2 , the reaction leading to the formation of ReOCl3[(C6H5)3P]2 was investigated with molybdenum compounds. Unexpected results led to extensive study of the reaction with molybdenum and tungsten. While this work was underway, synthesis of triphenylphosphonium salts and triphenylphosphine oxide complexes of several metals including tungsten, was published. Certain discrepancies in the reported infrared spectra resulted in a reinvestigation of the tungsten reactions. The interaction of MoO3 and hydrogen chloride in ethanol provided a simple method for the formation of the M0OCl52- ion. The effect of cation size on the formation of MoOCl52- or MoOCl41- salts has been studied.
