A number of 1,3-diarylpropenes, potential precursors of the allylic anions (I). have been synthesised, and the base catalysed equilibration between the double bond isomers (II) and (III) has been investigated. The equilibrium constants correlate satisfactorily with the substituent constant σ. N.m.r. shift reagents aided spectroscopic analysis of certain mixtures.
许多1,3-二芳基丙烯,烯丙基阴离子(I)的潜在前体。已合成,并且研究了双键异构体(II)和(III)之间的碱催化平衡。平衡常数与取代基常数σ令人满意地相关。Nmr变换试剂有助于某些混合物的光谱分析。
