Abstract
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 NH.sub.3:Mo (amount of molybdenum in the molybdenum source) of .gtoreq.1:1, preferably 1 3:1, more preferably 2 3:1, and most preferred 2.2 2.65:1.
