Method for preparation of organic molybdenum compounds
First Claim
1. A process for preparing a 2,4-heteroatom-substituted molybdena-3,3-dioxocycloalkane compound comprising the steps of selecting a starting material having the structural formula ##STR6## wherein X1 and X2 are selected from the group consisting of O, S or N and where n or m=1 when X1 or X2 is O or S and n or m=2 when X1 or X2 is N, y=0 or 1, and wherein R1, R2, R3, R4 and R5 are independently selected from the group consisting of hydrogen, alkyl, alkenyl, aryl, alkylaryl hydrocarbon group or fatty residue containing from 1 to 50 carbon atoms or polymeric residues having a molecular weight of 150 to 1200;
- and selected from poly-alpha-olefin, polypropene, polybutylene and polyisobutylene;
reacting the starting material with a molybdenum source sufficient to yield about 2 to 20 percent of molybdenum based on the weight of the molybdena-compound in the presence of water and a phase transfer agent of the formula ##STR7## wherein R6 is an alkyl group or fatty residue having 8 to 22 carbon atoms and X3 is a hydroxy or amino group at 60°
to 150°
C.;
removing the reaction water and diluent water and recovering the molybdena-compound of the formula ##STR8## wherein R1, R2, R3, R4, R5, X1, X2, n and m are defined and correspond to the starting materials in formula (I) and (II).

Abstract
A novel process for the preparation of 2,4-heteroatom substituted-molybdena-3,3-dioxacycloalkane compounds by reacting diol-, diamino-, thiol-alcohol and amino-alcohol compounds with a molybdenum source and in the presence of a phase transfer agent of the imidazoline type.
