Total Claims: 4
Claim 1
Independent Claim
111 words
THE PROCESS WHICH COMPRISES REACTING A METAL HYDROCARBON BORON HYDRIDE COMPOUND WHEREIN THE METAL IS SELECTED FROM THE GROUP CONSISTING OF ALKALI AND ALKALINE EARTH METALS AND THE HYDROCARBON GROUP CONTAINS UP TO ABOUT 10 CARBON ATOMS AND IS SELECTED FROM THE GROUP CONSISTING OF ALKYL, CYCLOALKYL, AND ARYL RADICALS WITH AN ALPHA-OLEFIN IN THE PRESENCE OF A TRIHYDROCARBON GROUP III-A METAL CATALYST WHEREIN THE HYDROCARBON GROUPS ARE SELECTED FROM THE GROUP CONSISTING OF ALKYL, CYCLOALKYL, AND ARYL RADICALS CONTAINING UP TO ABOUT 18 CARBON ATOMS TO FORM A METAL HYDROCARBON BORON COMPOUND HAVING AT LEAST ONE MORE HYDROCARBON RADICAL BONDED TO THE BORON THAND DOES SAID METAL HYDROCARBON BORON HYDRIDE.

Claim 3
Dependent Claim
57 words
AS A NEW COMPOSITION OF MATTER, METAL TETRAALKYL BORON COMPOUNDS WHEREIN THE METAL IS SELECTED FROM THE GROUP CONSISTING OF ALKALI AND ALKALINE EARTH METALS AND THE ALKYL GROUPS CONTAIN UP TO ABOUT 10 CARBON ATOMS COMPLEXED WITH AN ORGANIC SOLVENT CAPABLE OF DONATING ELECTRONS AND SELECTED FROM THE GROUP CONSISTING OF HYDROCARBON ETHERS AND HYDROCARBON AMINES.
