In this contribution, the high-yield preparation and optical properties of some donor-acceptor butadiene dyes, generated by coupling of different 1,1-diaryl-2-propyn-1-ols with indan-1,3-dione, are presented. The reactions, which involve the initial Meyer–Schuster rearrangement of the aromatic alkynols and subsequent condensation of the resulting enals with the β-dicarbonyl compound, proceeded cleanly
在这项贡献中,介绍了通过不同的1,1-二芳基-2-丙炔-1-醇与茚满-1,3-二酮偶联生成的一些供体-受体丁二烯染料的高产率制备和光学性质。该反应包括芳族炔醇的初始Meyer-Schuster重排以及随后使所得的烯类与β-二羰基化合物缩合,在催化量的廉价路易斯酸InCl的存在下,在MW辐射下于水中干净地进行反应。3。还包括对这些染料之一的单晶X射线衍射研究。
