Under conditions of mechanochemical and ultrasonic treatment, the P-KOH-HMPT triad reacts with phenylacetylene (75-80 deg C, 5 h) to form a mixture of stereoisomers of tristyrylphosphine and tristyrylphosphine oxide.The major reaction products are tris(Z,Z,Z-styryl)phosphine and tris(E,Z,Z-styryl)phosphine (Ia,b).These compounds isomerize on heating (160-165 deg C) into tris(E,E,E-styryl)phosphine.The latter, in contrast to its Z,Z,Z analog, is readily oxidizable by atmospheric oxygen into the corresponding E,E,E-isomer of tristyrylphosphine oxide.
