Patent ID: 7713900

Claim:
A catalyst comprising a transition metal bound to a compound of the formula wherein R is C 1 -C 20 alkyl, wherein said alkyl is optionally substituted with a substituent selected from the group consisting of hydroxyl, alkylamino, dialkylamino, cycloalkyl, alkenyl and alkoxy; C 3 -C 6 cycloalkyl, wherein said cycloalkyl is optionally substituted with a substituent selected from the group consisting of C 1 -C 20 alkyl and alkoxy; C 6 -C 12 aryl, wherein said aryl is optionally substituted with a substituent selected from the group consisting of (i) C 1 -C 20 alkyl, wherein said alkyl is optionally substituted with a substituent selected from the group consisting of hydroxyl, alkylamino, dialkylamino, cycloalkyl, alkenyl and alkoxy; (ii) C 3 -C 6 cycloalkyl, wherein said is optionally substituted with a substituent selected from the group consisting of C 1 -C 20 alkyl and alkoxy; and (iii) alkoxy; or heteroaryl, wherein said heteroaryl is optionally substituted with a substituent selected from the group consisting of (i) C 3 -C 6 alkyl, wherein said alkyl is optionally substituted with a substituent selected from the group consisting of hydroxyl, alkylamino, dialkylamino, cycloalkyl, alkenyl or alkoxy; and (ii) C 1 -C 6 alkoxy; R′ and R″ are independently C 3 -C 20 alkyl, wherein said alkyl is optionally substituted with a substituent selected from the group consisting of hydroxyl, alkylamino, dialkylamino, cycloalkyl, alkenyl and alkoxy; or an enantiomer thereof; or an enantiomeric mixture thereof.
