摘要：

ß-Cyclodextrin is a useful phase-transfer agent for the hydrogenation of conjugated dienes to monoolefins catalyzed by the in situ generated hydridopentacyanocobaltate anion. This reaction, which usually proceeds by 1,2-addition to the diene, is promoted by cerium or lanthanum chloride. Polyethylene glycol (PEG-400), with or without added lanthanide, can also be used as the phase-transfer agent for the reduction process. © 1990, American Chemical Society. All rights reserved.
