International audience; Schwartz's reagent, Cp2Zr(H)Cl, has traditionally been used as a stoichiometric reagent for the reduction of unsaturated organic molecules. Recently, methods to use Cp2Zr(H)Cl as a catalyst have been developed through turnover

Deoxydehydration (DODH) is one of the most promising tools to reduce the oxygen content of biomass (sugars and polyols) and provide analogues of platform chemicals that are derived from fossil resources. This reaction converts a vicinal diol into an

α-Aminoboronate salts are interesting examples of heteroatomic species containing adjacent nucleophilic centers. We have developed an acylation/arylation reaction using 2-bromobenzoyl chlorides as bis-electrophiles that harnesses the nucleophilicity
We report a catalytic reductive alkylation reaction of primary or secondary amines with carboxylic acids. The two-phase process involves silane mediated direct amidation followed by catalytic reduction.
