AB A family of gold(I) complexes of compositionAuCl(ADAP) (ADAP = alkoxydiaminophosphine) has beensynthetized through a one-pot simple protocol in which theADAP ligand is prepared in situ before reaction with the Au(I)source. Structural data demonstrate that these ADAP ligands exerta trans effect superior to those of phosphine or phosphite ligands.Evaluation of the buried volume (%VBur) indicates a sterichindrance higher than those of several NHC, PR3, and P(OR3)ligands, in the context of AuCl(L) complexes. These complexespromote the catalytic transfer of a carbene group from ethyldiazoacetate to alkenes and alkanes. In the case of styrene, both theCsp2−H bonds and the CC bond are functionalized, the relativeratio depending on the catalyst employed and correlating well withthe %VBur value. Data available allow proposing that these compounds display quite similar electronic properties but differ in stericproperties, a variable that can be readily controlled upon modifying the alkoxy group at the ADAP ligand by simply replacing thestarting alcohol employed in the synthesis.
