日期:2013.1.4
A palladium-catalyzed hydroalkylation reaction of protected allylicalcohols using alkylzinc bromide reagents is reported. This account includes numerous allylic, homoallylic, and bishomoallylic alcoholderivatives, all with a uniform selectivity of >20:1 for the anti-Markovnikov product. The reaction features the ability to deliver enantiomerically enriched alcohols in unfunctionalized regions, which

functionalization of C-Hbonds enables streamlined and sustainable solutions to problems in synthetic organic chemistry. In this Communication, we disclose an iron-based catalytic system for the functionalization of propargylic and allylic C-Hbonds. Inexpensive and readily-available cyclopentadienyliron(II) dicarbonyl complexes were employed as catalysts for a novel deprotonative activation mode for C-H functionalization
