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.

Improved, Acid-catalyzed Iodinating Procedures for Activated Aromatics with (Diacetoxyiodo)benzene as the Oxidant

Improved procedures for the oxidative, acid-catalyzed iodination of benzene, iodobenzene and several activated aromatics are presented to give mono-, di-, or triiodinated products in 40-82 percent yields. The reactions proceeded at room temperature in the anhydrous systems: arene or hetarene/diiodine/(diacetoxyiodo)benzene (2)/glacial acetic acid/acetic anhydride, acidified with catalytic amounts of concd. (98 percent) H2SO4. Within at most 15 minutes the iodine coloration faded; the following workups are explained. A similar treatment with dibromine gave tribromomesitylene (65 percent), dibromodurene (62 percent), and 2,7-dibromofluoren-9-one (73 percent). A review on the aromatic halogenation reactions with organic trivalent iodine reagents as the oxidants is presented below.

Selective Oxidative Iodination of Aromatic Compounds

Optimal conditions have been found for oxidative iodination of aromatic compounds in the system KI-H2SO4-HNO3-H2O in the presence of O2, and the kinetics and mechanism of the reaction have been studied. The process involves oxidation of I- to I+ with NO+2 ion, arene iodination with I+, and oxidation of HNO2 to HNO3 with oxygen.
