  • Title: (NHC)CuH-catalyzed entry to allenes via propargylic carbonate S(N)2'-reductions.
    Author: Deutsch C, Lipshutz BH, Krause N.
    Journal: Org Lett; 2009 Nov 05; 11(21):5010-2. PubMed ID: 19863153.
    Abstract:
    The copper hydride-catalyzed S(N)2'-reduction of propargylic carbonates provides an efficient route to functionalized allenes. The method takes advantage of the stabilizing effect of NHC ligands on CuH and combines high reactivity and stereoselectivity with excellent tolerance toward reactive functionalities.
