摘要：

Syntheses of 2,5-diarylthiazole and 2,5-diarylthiophene derivatives bearing ethynylene and thienylene spacers are performed. With the methods for coupling reactions of terminal alkynes and at the CH bond of heteroaromatic compounds, which we have developed, five kinds of thiazole and thiophene derivatives 3-7 are prepared. Spectroscopic characteristics of 3-7 are also measured. (c) 2006 Elsevier Ltd. All rights reserved.
