Gold-catalyzed cyclization of 1,5-diynes with ketones as reagents and solvent provides diversely substituted vinyl ethers under mild conditions. The regioselectivity of such gold-catalyzed cyclizations is usually controlled by the scaffold of the diyne. H

In-sertion of metal: Catalytic amounts of InCl3 allow the insertion of aluminum and zinc into aromatic 1,2-dibromides or 1,2-bromotriflates (see scheme). These 1,2-dimetallic species can undergo Cu or Pd-catalyzed acylations, allylations, or cross-couplings. Copyright

1,6-Disubstituted (E,Z,E)-1,3,5-hexatrienes (4 and 5) were prepared by vicinal twofold Heck coupling reactions from 1,2-dibromocyclopentene (1), 1,2-dibromocyclohexene (2), 1,2-diiodocyclopentene (8), 1,2-diiodocyclohexene (9), 1-bromo-2-trifluoromethanes
STUDIES ON THE OXIDATION OF HYDRAZONES WITH IODINE AND WITH PHENYLSELENENYL BROMIDE IN THE PRESENCE OF STRONG ORGANIC BASES; AN IMPROVED PROCEDURE FOR THE SYNTHESIS OF VINYL IODIDES AND PHENYL-VINYL SELENIDES

The oxidation of hydrazones by iodine in the presence of strong organic bases (guanidines) has been studied.Improved yields of vinyl iodides can be obtained by inverse addition using dry solvents and with a final heating period where appropriate.The reaction has been extended to various dihydrazones with interesting results.In complementary studies hydrazones have been oxidized by phenylselenyl bromide in the presence of strong organic bases to give the corresponding phenyl vinyl selenides in good yield.
