experimental and theoretical methods, the reaction mechanism for addition/oxidative cross-coupling of internal alkynes with azoles has been investigated. Theoretical calculations reveal that the metalation/deprotonation of azole could occur with either rhodium or copper species. When azolylrhodium is formed, an alkyne could insert into the Rh–C bond. Another azolyl group could then transfer to rhodium from azolylcopper

The photoluminescence (PL) and electroluminescence (EL) properties of two highlyefficient excited state intramolecular proton transfer (ESIPT) molecules, 2-(2′-hydroxyphenyl)oxazoles containing one triphenylamine (TPA) (1) and two TPAs (2) respectively, are studied systematically. The enol-forms of both 1 and 2 possess highly hybridized local and charge transfer (HLCT) excited state character, while

Polystyrene-SH resin, prepared from Merrifield resin in two steps, was converted to polystyrene-SO2-CH2-NC in three steps. This resin functions as a solid-phase equivalent of p-tolylsulfonylmethyl isocyanide (TosMIC). Thus, reaction with aromatic aldehydes and tetrabutylammonium hydroxide as base yields 5-aryloxazoles.
