Patent ID: 8642812

Claim:
A process comprising: combining, in fluid communication: (a) an addition reaction reagent that comprises at least one terminal olefin moiety; (b) a sterically hindered Lewis acid comprising B, Al, Ga, In, Ti, Zr or Hf; and (c) a sterically hindered Lewis base comprising N, P, S, or O; and obtaining an addition reaction product, wherein the sterically hindered Lewis base is a compound of formula II and the sterically hindered Lewis acid is a compound of formula III, wherein the compounds of formula II and III are: where R 1 , R 2 , R 4 , R 5 , and R 7 are independently: C 8 -C 10 aryl; C 6 -C 8 cycloalkyl: C 8 -C 10 aryl having at least one C 1 -C 20 alkyl substituent; C 5 -C 8 cycloalkyl having at least one C 1 -C 20 alkylsubstituent; C 4 -C 20 branched alky; C 16 -C 20 linear alkyl; —OR;—NRR′; —PRR′; or —SR; R 6 is C 1 -C 38 alkyl; C 6 -C 38 aryl; C 8 -C 30 cycloalkyl; —OR; —NRR′; —PRR′; —SR; H; or F; R and R′ are, independently: C 6 -C 10 aryl; C 6 -C 8 cycloalkyl; C 6 -C 18 aryl having at least one C 1 -C 20 alkyl substituent; C 6 -C 8 cycloalkyl having at least one C 1 -C 20 substituent; C 4 -C 20 branched alkyl; or C 8 -C 20 linear alkyl; A is: N; P; S; or O; with the proviso that when A is S or O, R 2 is a nullity; and M is: B, Al, Ga, In, Ti, Zf or Hf.
