Preparation of cyclopentadienyl coordination compounds of groups viii and ib metals

Claim 1

THE PROCESS FOR FORMING A CYCLOPENTADIENYL METAL COORDINATION COMPOUND WHEREIN THE METAL IS SELECTED FROM GROUPS VIII AND IB OF THE PERIODIC TABLE AND WHEREIN THE METAL ACHIEVES THE ELECTRON CONFIGURATION OF THE NEXT HIGHER RARE GAS BY COORDINATION WITH A CYCLOPENTADIENYL HYDROCARBON RADICAL CONTAINING FROM FIVE TO ABOUT 13 CARBON ATOMS IN ADDITION TO ELECTRON DONOR GROUPS SELECTED FROM THE CLASS CONSISTING OF RADICALS AND MOLECULAR SPECIES WHICH CONTAIN LABILE ELECTRONS, SAID RADICALS AND MOLECULAR SPECIES BEING SELECTED FROM THE CLASS CONSISTING OF THE HYDROGEN ATOM, UNIVALENT ORGANIC HYDROCARBON RADICALS OF 1-12 CARBON ATOMS, THE CYANIDE RADICAL, CARBON MONOXIDE, AMMONIA, TERT-AMINES WHOSE ORGANIC RADICALS ARE UNIVALENT ORGANIC HYDROCARBON RADICALS OF 1-12 CARBON ATOMS, TERT-PHOSPHINES WHOSE ORGANIC RADICALS ARE UNIVALENT ORGANIC HYDROCARBON RADICALS OF 1-12 CARBON ATOMS, PHOSPHORUS TRIHALIDES AND NITRIC OXIDE, SUCH THAT SAID ELECTRONS ASSUME MORE STABLE CONFIGURATIONS IN THE MOLECULE WHEN ASSOCIATED WITH THE METAL TO GIVE IT THE CONFIGURATION OF THE NEXT HEAVIER RARE GAS, WHICH METHOD COMPRISES REACTING A COMPOUND SELECTED FROM THE GROUP CONSISTING OF CYCLOPENTADIENYL GRIGNARD REAGENTS WHEREIN THE CYCLOPENTADIENYL RADICAL IS A CYCLOPENTADIENYL HYDROCARBON RADICAL OF 5 TO ABOUT 13 CARBON ATOMS, ALKALI METAL CYCLOPENTADIENYL COMPOUNDS WHEREIN THE CYCLOPENTADIENYL RADICAL IS A CYCLOPENTADIENYL HYDROCARBON RADICAL OF 5 TO ABOUT 13 CARBON ATOMS, AND CYCLOPENTADIENYL ZINC HALIDES WHEREIN THE CYCLOPENTADIENYL RADICAL IS A CYLCOPENTADIENYL HYDROCARBON RADICAL OF 5 TO ABOUT 13 CARBON ATOMS, WITH A HALIDE OF A METAL SELECTED FROM GROUPS VIII AND IB OF THE PERIODIC TABLE IN A NON-REACTIVE LIQUID MEDIUM TO PRODUCE A DICYCLOPENTADIENYL-GROUP VIII-IB-METAL COMPOUND WHEREIN EACH CYCLOPENTADIENYL RADICAL IS A CYCLOPENTADIENYL HYDROCARBON RADICAL OF 5 TO ABOUT 13 CARBON ATOMS AND REACTING SAID DICYCLOPENTADIENYL-GROUP VIIIIB-METAL COPOUND WITH A COMPOUND CAPABLE OF CONTRIBUTING ELECTRON DONOR GROUPS TO THE METAL ATOM, SAID ELECTRON DONOR GROUPS BEING SELECTED FROM THE CLASS CONSISTING OF RADICALS AND MOLECULAR SPECIES WHICH CONTAIN LABILE ELECTRONS, SAID RADICALS AND MOLECULAR SPECIES BEING SELECTED FROM THE CLASS CONSISTING OF THE HYDROGEN ATOM, UNIVALENT ORGANIC HYDROCARBON RADICALS OF 1-12 CARBON ATOMS, THE CYANIDE RADICAL, CARBON MONOXIDE, AMMONIA, TERT-AMINES WHOSE ORGANIC RADICALS ARE UNIVALENT ORGANIC HYDROCARBON RADICALS OF 1-12 CARBON ATOMS, TERT-PHOSPHINES WHOSE ORGANIC RADICALS ARE UNIVALENT ORGANIC HYDROCARBON RADICALS OF 1-12 CARBON ATOMS, PHOSPHORUS TRIHALIDES AND NITRIC OXIDE.
