Asymmetric Intermolecular Heck Reaction of Propargylic Acetates and Cycloalkenes to Access Fused Cyclobutenes

An asymmetric Heck annulation of propargylic acetates with several types of cyclic olefins affords highly strained cyclobutenes in high enantioselectivity.

SUBSTITUTED ETHYNYL GOLD-NITROGENATED HETEROCYCLIC CARBENE COMPLEX AND ORGANIC ELECTROLUMINESCENT DEVICE USING SAME

The present invention provides a substituted ethynyl gold-nitrogen containing heterocyclic carbene complex represented by the general formula (1): wherein L represents a nitrogen containing heterocyclic carbene ligand; and X represents an alkyl group, a cycloalkyl group, an aryl group, an aralkyl group or a heterocyclic group; in which one or more hydrogen atoms on the carbon atom(s) of X may be replaced by a halogen atom, an alkyl group, a cycloalkyl group, an alkenyl group, an aryl group, an aralkyl group, an alkoxy group, an aryloxy group, a dialkylamino group, an acyl group or an arylcarbonyl group; and, when more than one hydrogen atom on the carbon atom(s) of X is replaced by the alkyl group, the alkenyl group, the aryl group, the aralkyl group, the alkoxy group, the aryloxy group, the dialkylamino group, the acyl group or the arylcarbonyl group, the adjacent groups may be bonded together to form a ring, a method for preparing the same, and an organic electroluminescent device comprising the substituted ethynyl gold-nitrogen containing heterocyclic carbene complex in at least one organic compound thin layer.

Synthesis of Some Substituted Dimethyl and Diethyl 4-(Phenylethynyl)-2,6-pyridinedicarboxylates

Substituted dimethyl and diethyl 4-(phenylethynyl)-2,6-pyridinedicarboxylates were prepared by coupling reactions between dialkyl 4-halo-2,6-pyridinedicarboxylates and terminal arylacetylenes in the presence of an organopalladium catalyst and copper(I) iodide in a suitable solvent system.The terminal acetylenes needed in this work were synthesized from the corresponding aryl halides using either (trimethylsilyl)acetylene or 2-methyl-3-butyn-2-ol followed by deprotection of the triple bond, depending on the nature of the compound in question.
