Class Information
Number: 987/45
Name: Organic compounds containing a bi, sb, as, or p atom or containing a metal atom of the 6th to 8th group of the periodic system > Phosphorus compounds (9/02; 9/06) > Compound contains a ring which is devoid of a metal atom and contains at least one p atom as ring member (9/6564; 9/6564v; 9/6568; 9/6568b; 9/6568c; 9/6568d; 9/6568e; 9/6568f) > Ring contains o and p only, or may include in addition to the required o and p, only c (9/6571) > Contains p and o as ring atoms and wherein the p atom is directly bonded to a c atom (9/6571l) > P atom bonded to c is bonded to an o atom which is in the same ring as p (9/6571l2; 9/6571l6)
Description: Subject matter wherein the ring phosphorus atom is bonded directly to a single ring oxygen atom.
