Phosphorus supported carbene transition metal complexes

A complex having the formula:

• 11
• wherein M is a metal atom selected from the group consisting of transition metal, lanthanides and group 11 and 12 post transition metals;
• R1, R2, R3 and R4 are independently selected from the group consisting of a hydrogen atom, a saturated or unsaturated straight chained, branched or cyclic hydrocarbyl radical which is unsubstituted or substituted by one or more substituents selected from the group consisting of a halogen atom and C1-6 alkyl radical;
• R7 and R8 are independently selected from the group consisting of a hydrogen atom, a halogen atom, an amide —NR1R2, imide ═NR1, a alkoxide or aryl oxide group —OR1, and an —OSi(R1)3 group where R1 and R2 are defined above, a saturated or unsaturated straight chained, branched or cyclic hydrocarbyl radical which are unsubstituted or substituted by a halogen atom or a C1-6 alkyl radical or a Lewis base (neutral coordinating ligands);
• and each R5 is independently selected from the group consisting of radicals selected from the group consisting of saturated and unsaturated straight chained, branched and cyclic hydrocarbyl radicals;
• radicals of the formula Si(R6)3 wherein each R6 is independently selected from the group consisting of saturated or unsaturated straight chained, branched or cyclic hydrocarbyl radicals;
• and radicals of the formula III:
• 12
• wherein R9, R10, R11 and R12 are independently selected from the group consisting of a hydrogen atom, a fluorine atom, a NO2 radical, a C1-6 alkyl radical, and a C8-12 aryl radical and E is an endocyclic nitrogen atom or a C—CN group.
