abstract = {A family of gold(I) complexes of composition
AuCl(ADAP) (ADAP = alkoxydiaminophosphine) has been
synthetized through a one-pot simple protocol in which the
ADAP ligand is prepared in situ before reaction with the Au(I)
source. Structural data demonstrate that these ADAP ligands exert
a trans effect superior to those of phosphine or phosphite ligands.
Evaluation of the buried volume (%VBur) indicates a steric
hindrance higher than those of several NHC, PR3, and P(OR3)
ligands, in the context of AuCl(L) complexes. These complexes
promote the catalytic transfer of a carbene group from ethyl
diazoacetate to alkenes and alkanes. In the case of styrene, both the
Csp2−H bonds and the CC bond are functionalized, the relative
ratio depending on the catalyst employed and correlating well with
the %VBur value. Data available allow proposing that these compounds display quite similar electronic properties but differ in steric
properties, a variable that can be readily controlled upon modifying the alkoxy group at the ADAP ligand by simply replacing the
starting alcohol employed in the synthesis.},
