Abstract

PURPOSE:To obtain a new compound useful as a nonlinear optical material, an intermediate, etc., for coloring matters or liquid crystal compounds. CONSTITUTION:This compound is expressed by formula I (R is H, dialkylamino or alkoxy), e.g. 1-phenyl-4-(3-hydroxy-4-nitrophenyl)-1,3-butdaiene. The compound expressed by formula I is obtained by reacting a butadiene compound expressed by formula II with t-butoxypotassium (in an amount of 15 molar equiv. based on the compound expressed by formula II) in a polar solvent (preferably dimethylformamide) at ambient temperature.

As a conventional technique for producing a butadiyne compound from a butadiene compound, a method is generally used in which the ethylene group of the butadiene compound is brominated with bromine and then dehydrobrominated with a base. However, this method is complicated because it is a two-step reaction of "bromination" and "dehydrobromination", and bromine used for bromination eventually becomes a waste, which is expensive.

The target substance (compound (5) and compound (6)) was separated and purified by treating the residue by column chromatography packed with silica gel (Wakogel C-200) using benzene as a dissolving agent / developing eluent. The separated state was visually confirmed by the colored band of silica gel. The compound (6) was eluted first. Each was recrystallized from benzene: ethanol (1: 1) to obtain the desired product as shown below.
