WebOrganophosphine. Organophosphines are organophosphorus compounds with the formula PR n H 3−n, where R is an organic substituent. These compounds can be classified according to the value of n: primary phosphines ( n = 1), secondary phosphines ( n = 2), tertiary phosphines ( n = 3). All adopt pyramidal structures.
