Reactions in which Phosphorus is Electrophilic

Reactions in which Phosphorus is Electrophilic.—Further study has been made of the reactions between chlorodialkylphosphines (26) and phosphites or phosphonites.28 By appropriate choice of the alkyl groups in (26), redistribution reactions can be inhibited and good yields of products (27) with P—P bonds are obtained.28 

Displacement reactions at Pm have been carried out with the thallium salt of cyclopentadiene, and various phosphinocyclopentadienes (28) isolated.29 Triphenyl-
