Phosphine, (2-bromophenyl)dichloro-, 2,991 Phosphine, (w-chloroalkyl)dichloro-, 2, 991 Phosphine, chlorodimethyl-, 2, 991 Phosphine, chloro(dimethylamino)-, 2, 991 Phosphine, chlorodiphenyl-, 2, 990 Phosphine, cyclohexyl(o-anisyl)methyl-rhodium complexes asymmetric hydrogenation, 6, 251 Phosphine, [(dialkylphosphino)alkyl]diphenyl-, 2, 994 Phosphine, dichloromethyl-, 2, 991 Phosphine, dichlorophenyl-, 2, 990 Phosphine, diethylphenyl-, 2, 992 Phosphine, dimethyl-, 2,992 Phosphine, dimethylphenyl-, 2,992 Phosphine, diphenyl-, 2, 992 Phosphine, ethyldiphenyl-, 2, 992 Phosphine, ethylenebis(diethyl-, 2, 993 Phosphine, ethylenebis(diphenyl-, 2,993 Phosphine, ethylenebis(phenyl-, 2,992 Phosphine, ethylidynetris[methylene(diphenyl-, 2,994 Phosphine, [(ethylphenylphosphino)hexyl]diphenyl-, 2, 994... 

Bis(diphenylphosphino)methyl-lithium, from methyl-lithium and bis-(diphenylphosphino)methane, gave the compound (1) with chlorodiphenyl-phosphine. ... 

B. From Metallated Phosphines.—Lithium diphenylphosphide and ethylene oxide produce (7), which when added to chlorodibutyl- or chlorodiphenyl-phosphine yields 2-diphenylphosphinoethyl phosphinites (8). 

B. Reactions.—(/) Nucleophilic Attack at Phosphorus. A reinvestigation of the reaction between phosphorus trichloride and t-butylbenzene in the presence of aluminium chloride has shown that the product after hydrolysis is the substituted phosphinic acid (11), and not the expected phosphonic acid (12). Bis(A-alkylamino)phosphines have been reported to attack chlorodiphenyl phosphine with nitrogen, in the presence of a base, to give bis-(A-alkyl-A-diphenylphosphinoamino)phenylphosphines (13). In (13), the terminal phosphorus atoms are more reactive than the central one towards sulphur and towards alkyl halides. 

A rationalization of the reactions between )8-keto-alcohols and halogenophosphines has been presented by a Russian group. In particular, the reaction between dichloro(phenyl)phosphine (26) and diacetone alcohol to give the oxide (27) has been shown to occur in stages (Scheme 9), and physical and chemical evidence has been presented for the initial formation of mesityl oxide (28) and the acid (29), followed by the addition product (30). A less detailed study of the analogous reaction of chlorodiphenyl-phosphine (5) with diacetone alcohol has also been published. ... 

The structure of the major product from the reaction of chlorodiphenyl-phosphine with hydrazine hydrochloride has now been shown to be (23 X = Cl), rather than the linear phosphazene (H2N-Ph2P=N Pha-P=N-Ph2PNH2) Cl . A number of other salts based on [(23) X = I,... 

A bifunctional flame retardant such as Ai5-(chlorodiphenyl phosphine) dechlorane would have additional efficiency due to crosslinking [30]. Mixtures of flame retardants can act synergistically, reportedly via the formation of a bifunctional compound which is capable of...
