R-220.127.116.11 Organic derivatives of the trivalent phosphorus, arsenic, antimony, and bismuth parent hydrides are named substitutively on the basis of parent hydride names such as phosphane, diphosphane, arsane, stibane, bismuthane, etc. (see R-2.1 and R-2.2.2). In these recommendations, the names phosphine, arsine, stibine, and bismuthine are not encouraged.
Examples to R-18.104.22.168
R-22.214.171.124 Organic derivatives of pentavalent phosphorus, arsenic, antimony, and bismuth are named either on the basis of parent hydride names such as -phosphane, -arsane, and , -diphosphane, etc., or on the basis of parent hydride names such as phosphorane and arsorane, the former method being preferred.
