Abstract: It has now been discovered that oligomers of C.sub.6 - C.sub.20 alpha-olefins, such as 1-decene, with branch ratios below 0.19 and high viscosity indices (HVI) can be functionalized to provide unique phosphite derivatives. Functionalized polyalpha-olefin lubricants compositions are prepared with superior properties by adding functionalized organophosphites to the olefinic bond of HVI-PAO. The invention encompasses a process for the preparation of lubricant range hydrocarbons containing phosphonate functional groups, comprising;reacting olefinic C.sub.20 + polyalpha-olefin oligomers having a branch ratio of less than 0.19 and phosphite ester in a mixture with peroxide catalyst at elevated temperature whereby phosphite ester adduct of said polyalpha-olefin is formed;separating said reaction mixture products and recovering said adduct.

Abstract: New organic phosphorus compounds, comprised of hetero-phosphacycloalkanes whose phosphorus atom forms a complex with a borane. They can be prepared by the action of a borane on a hetero-phosphacycloalkane, within a solvent, at temperatures ranging from -20.degree. to +60.degree. C. Their transformation into other derivatives, phosphinites or phosphines in particular, can be carried out without any modification in the chirality of the initial complex. An especially useful application is their conversion into highly optically active phosphines, used in particular as catalysts in various reactions.
