Functionalized aluminum reagents
The invention is directed to functionalized aluminum reagents of formula 1 where R is a linear or branched alkane group containing 1 to 8 carbon atoms, and R 1 is phenylene, or a linear or branched alkane diyl group containing 2 to 10 carbon atoms, or a combination of one or more phenylene groups and one or more linear or branched alkane diyl groups containing 1 to 10 carbon atoms; Q is of formula 2 where R 3 and R 4 are independently phenyl or a linear or branched alkyl group containing 1 to 10 carbon atoms, or R 3 and R 4 taken together with the nitrogen atom represent a nitrogen containing heterocyclic group containing from 4 to 12 carbon atoms.
