Patent ID: 6846769

Claim:
Vanadium-imido-phosphoraneiminato compounds, which correspond to the general formula R—N═VCl 2 (NPR 1 R 2 R 3 ) (I) or R—N═VXY(NPR 1 R 2 R 3 ) (II), wherein R represents a C 1 -C 10 -alkyl group, a C 6 -C 14 -aryl group or a C 1 -C 10 -heteroaryl group, wherein X,Y are each independently of the other different or identical monoanionic ligands which may be bonded to one another and/or to the R group of the imide, or its substituents, and/or to the radicals R 1 , R 2 , R 3 of the iminophosphorane, or wherein X and/or Y is likewise an iminophosphorane having radicals R 4 , R 5 , R 6 and R 7 , R 8 , R 9 wherein R 1 , R 2 , R 3 and, optionally, R 4 , R 5 , R 6 , R 7 , R 8 , R 9 are each independently of the others different or identical C 1 -C 10 -alkyl, C 6 -C 14 -aryl, C 1 -C 10 -alkoxy groups which may be bonded to one another and/or to the R group of the imide, or its substituents, and/or to the radicals R 1 , R 2 , R 3 of the iminophosphorane, or alternatively one or more substituents of the phosphorus are bonded to the phosphorus via heteroatoms selected from N, O, and S.
