CO extrusion in homogeneous gold catalysis: Reactivity of gold acyl species generated through water addition to gold vinylidenes

Herein, we describe a new gold-catalyzed decarbonylative indene synthesis. Synergistic σ,π-activation of diyne substrates leads to gold vinylidene intermediates, which upon addition of water are transformed into gold acyl species, a type of organogold compound hitherto only scarcely reported. The latter are shown to undergo extrusion of CO, an elementary step completely unknown for homogeneous gold catalysis. By tuning the electronic and steric properties of the starting diyne systems, this new reactivity could be exploited for the synthesis of indene derivatives in high yields.

Process for preparing 2-aryl-substituted indenes

A process is disclosed for preparing 2-aryl-substituted indenes by reacting an indene with an arene compound substituted with an halogen atom, preferably a iodine atom, or with an organosulphonate group, said reaction being carried out in a basic medium i

Response of Acidity and Magnetic Rtesonance Properties to Aryl Substitution in Carbon Acids and Derived Carbanions: 2- and 3-Arylindenes

Substitution in the aryl ring of 2- and 3-arylindenes has been used to examine the acidity of these hydrocarbons and the charge density and ion pair structure of their anions.Acidities were measured for the 2-arylindenes both in pure Me2SO and in Me2SO-H2
