Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
70 words
AN ORGANOMETALLIC COMPLEX OF VANADIUM TRIHALIDE IN WHICH THE HALOGEN HAS AN ATOMIC NUMBER BELOW 36 WITH FROM ONE TO TWO MOLES, INCLUSIVE, PER MOLE OF VANADIUM TRIHALIDE, OF A MONOETHYLENICALLY UNSATURATED COMPOUND OF FORMULA H2C=CRX, WHERE R IS A RADICAL SELECTED FROM THE GROUP CONSISTING OF HYDROGEN, HALOGEN AND ALKYL, AND X IS A RADICAL SELECTED FROM THE GROUP CONSISTING OF HYDROGEN, HALOGEN, ALKYL, ARYL, ALKYCLARBONYLOXY, ALKOXYCARBONYL AND CYANO.
Claim 2
Dependent Claim
70 words
AN ORGANOMETALLIC COMPLEX OF VANADIUM TRIHALIDE IN WHICH THE HALOGEN HAS AN ATOMIC NUMBER BELOW 36 WITH FROM ONE TO TWO MOLES, INCLUSIVE, PER MOLE OF VANADIUM TRIHALIDE, OF A MONOETHYLENICALLY UNSATURATED COMPOUND OF FORMULA H2C=CRX, WHERE R IS A RADICAL SELECTED FROM THE GROUP CONSISTING OF HYDROGEN, HALOGEN AND ALKYL, AND X IS A RADICAL SELECTED FROM THE GROUP CONSISTING OF HYDROGEN, HALOGEN, ALKYL, ARYL, ALKYCLARBONYLOXY, ALKOXYCARBONYL AND CYANO.
Claim 3
Dependent Claim
95 words
PROCESS WHICH COMPRISES REACTING A VANADIUM TETRAHALIDE OF HALOGEN OF ATOMIC NUMBER BELOW 36 WITH FROM ONE TO TWO MOLES, PER MOLE OF SAID TETRAHALIDE, OF AN UNSATURATED COMPOUND OF FORMULA H2C=CRX, WHERE R IS A RADICAL SELECTED FROM THE GROUP CONSISTING OF HALO GEN, HYDROGEN AND ALKYL AND X IS A RADICAL SELECTED FROM THE GROUP CONSISTING OF HYDROGEN, HALGEN, ALKYL, ARYL, ALKYLCARBONYLOXY, ALKOXYCARBONYL AND CYANO AND SEPARATING FROM THE REACTION MIXTURE OF ORGANOMETALLIC COMPLEX OF VANADIUM TRIHALIDE WITH FROM 1 TO 2 MOLES, INCLUSIVE, PER MOLE OF VANADIUM TRIHALIDE, OF SAID UNSATURATED COMPOUND.
Claim 4
