PROCESS FOR THE PREPARATION OF ORGANO-MOLYBDENUM COMPOUNDS

摘要

This invention is a process for preparation of 2,4-heteroatom-substituted molybdena- 3,3-dioxocycloalkane compounds by reacting diol-, diamino, thiol-alcohol- and amino- alcohol-compounds with the following reagents: ammonium molybdate (or in situ produced ammonium molybdate by the reaction of ammonia with molybdenum trioxide or molybdic acid) as a molybdenum source, ammonia as an additional or secondary reagent or promoter, in molar ratio NH₃ :Mo (amount of molybdenum in the molybdenum source) of =1 :1, preferably 1-3:1, more preferably 2-3:1, and most preferred 2.2-2.65 : 1.
