摘要

Abstract The title effect has been investigated in the homologous series of erythro-and threo- 5, 6-dihalodecanes (X= Br, Y= I; X= Cl, Y= I; X= F, Y= I; X= Br, Y= Br; X= Cl, Y= Br; X= F, Y= Br; X= Cl, Y= Cl; X= F, Y= Cl). It has been found that proportion of syn-elimination in the overall reaction varies with the variation of the halogen leaving groups in the order I< Br< Cl< F, ranging between the extreme 3-30% in the erythro-and 5-60% in the threo-series. ...
