Solid-state and dynamic solution behavior of a cationic, two-coordinate gold(I) π-allene complex
Abstract
The cationic gold π-allene complex {[P(t-Bu)2o-biphenyl] Au[η2-H2C=C=C(CH3)2]} +SbF6-
was isolated in 98% yield from reaction of 3-methyl-1,2-butadiene with a mixture of
[P(t-Bu)2o-biphenyl]AuCl and AgSbF6 and was characterized by X-ray crystallography
and variable-temperature NMR spectroscopy. These studies revealed preferential binding
of gold to the less substituted C=C bond of the allene in both the solid state and
solution and also revealed fluxional behavior consistent with π-face exchange of the
allene ligand via an η1-C2 allene intermediate or transition state. © 2010 American

Research in the Widenhoefer group is directed toward the development and mechanistic
analysis of new organotransition metal-catalyzed transformations for application in
the synthesis of functionalized organic molecules. In particular, our group has a
long-standing interest in the functionalization of C–C multiple bonds with carbon
and heteroatom nucleophiles catalyzed by electrophilic late transition metal complexes,
with a recent focus on the synthetic and mechanistic aspect of gold(I) pi-acti
