Hydrosilylation of aldehydes and ketones catalyzed by [Ph3P(CuH)]6
摘要:
Exposure of an aldehyde or ketone to less than or equal to 5 mol% (in copper) of Stryker's reagent [Ph3P(CuH)](6) in the presence of one of several silanes affords the corresponding protected alcohol in high yields. Aldehydes can be cleanly reduced in the presence of ketones. (C) 2001 Elsevier Science B.V, AH rights reserved.
