Class Information
Number: 987/232
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) > P is pentavalent and contains the structure p-(o-c) or p-(o-z) where z indicates an atom other than h (9/09; 9/09a1) > Containing the structure p-(o-unsubstituted alkyl) wherein all of the o atoms in the molecule which are single bonded to the p atom are bound directly to carbon radicals containing only carbon and hydrogen atoms (9/11)
Description: Subject matter wherein all of the carbon atoms which are directly bonded to the oxygen atoms which are directly bonded to the P atom are either substituted solely by hydrogen atoms or are part of a moiety containing only carbon and hydrogen atoms.
