Cs. Ge et al., THE KINETIC RANGE OF CARBENE-PYRIDINE YLIDE FORMING REACTIONS, Journal of the Chemical Society, Chemical Communications, (12), 1994, pp. 1479-1480
Absolute rate constants for the ylide-forming reactions of 16 carbenes
with pyridine range from 1.4 x 10(10) to 1.2 x 10(5) dm(3) mol(-1) s(
-1), and can be rationalized by frontier molecular orbital theory.
