Vv. Platonov et al., Genetic relation of adamantanes from extracts and semicoking tars of lignites with the initial biological material, RUS J AP CH, 72(11), 1999, pp. 2020-2027
A genetic relation was revealed of adamantanes from extracts and semicoking
tars of lignites with the relic terpenoid and steroid compouns, and probab
le pathways were suggested for transformation of the initial natural struct
ures into adamantanes. The qualitative and quantitative compositions of ada
mantanes from crude oil and coal were compared.
