The mechanism of a recently reported first mono-reduction of cyclic 1,3-diesters (Meldrum's acids) to β-hydroxy acids with SmI 2-H2O has been studied using a combination of reactivity, deuteration, kinetic isotope and radical clock e
Synthesis of quaternary carbon centers via hydroformylation

The application of hydroformylation to the synthesis of quaternary carbon centers is reported. The synthesis of the highly substituted carbon is achieved by applying a catalytic amount of 1. Ligand 1 serves as a catalytic directing group by covalently and reversibly binding to both the substrate and catalyst. The intramolecular nature of the directing group strategy accelerates the hydroformylation reaction such that the reaction is performed at mild temperatures (35-55 °C) and with excellent regioselectivity (b:l > 94:6).
Nickel-catalyzed highly selective hydrovinylation of α-ketals of vinylarenes
Zhang, Qi,Zhu, Shou-Fei,Qiao, Xiang-Chen,Wang, Li-Xin,Zhou, Qi-Lin
supporting information; experimental part, p. 1507 - 1510 (2009/07/30)
A nickel-catalyzed hydrovinylation of α-ketal derivatives of vinylarenes has been developed, providing a new method for preparing functional olefins with a quarternary carbon center in high yields and selectivities.
