An approach based on the molecular topology is used to study the relationship between the boiling points of alkyl benzenes, alkyl biphenyls and their molecular sturctures, and a quantitative relation is developed which can be used to characterize the structure-property relationship and to predict the boiling points of alkyl benzenes and alkyl biphenyls.

In this paper the cross-coupling reaction of alkyl bromides with the Grignard reagent of p-bromobiphenyl provided a series of 4-alkylbiphenyl class compounds by using cupric chloride as the catalyst for C—C bond formation in yields of about 91%.
