Two rhodium(II) ions work together: [Rh2(S-tbpttl)4] is an exceptionally effective catalyst for enantioselective cyclopropenation reactions of 1-alkynes with α-alkyl-α-diazoacetates (see scheme). Cyclopropenation is preferred over alkene formation through a 1,2-hydride shift. Copyright
One-pot ester synthesis from allyl and benzyl halides and alcohols by palladium-catalyzed carbonylation

experimental part, p. 423 - 430 (2012/03/11)
A mild and efficient one-pot synthesis of esters based on the Pd-catalyzed alkoxy- and aryloxycarbonylation of allylic and benzylic halides is described. The methodology has been applied to primary, secondary, and tertiary alcohols as well as to phenol derivatives. The O-protection of some biologically relevant molecules is also reported.
