Wj. Dubay et al., LITHIUM COBALT-BIS-DICARBOLLIDE - A NOVEL LEWIS-ACID CATALYST FOR THECONJUGATE ADDITION OF SILYL KETENE ACETALS TO HINDERED ALPHA,BETA-UNSATURATED CARBONYL-COMPOUNDS, Journal of organic chemistry, 59(23), 1994, pp. 6898-6899
The novel Lewis acid, lithium cobalt-bis-dicarbollide (1), in which th
e lithium ion is weakly coordinated to the Co(B9C2H11)(2)(1-)anion, is
an effective, soluble catalyst for Mukaiyama-Michael reactions.
