Abstract
A series of new secondary phosphine
oxide (SPO)–gold(I)
complexes have been synthesized and characterized by X-ray crystallography.
Complexes exhibited dimeric structures interconnected by O–H···Cl
hydrogen bonds. Their first use in homogeneous catalysis is reported
and suggests a broad field of application in prototypical enyne cycloisomerization
and hydroxy- and methoxycyclization reactions
