TL;DR: In this paper, a stepwise procedure allowing the formation of symmetrical arylphosphines is described, which relies on the use of preformed functionalized aromatic organozinc reagents to perform arylations of chlorophosphines.
Abstract: A stepwise procedure allowing the formation of symmetrical arylphosphines is described. It relies on the use of preformed functionalized aromatic organozinc reagents to perform arylations of chlorophosphines. Some preliminary results concerning the synthesis of unsymmetrical diarylphenylphosphines through sequential coupling of organozinc species with dichlorophenylphosphine are also reported.

TL;DR: The solubilities of dichlorophenylphosphine sulfide (DCPPS) and bis(4-carboxyphenyl)phenyl phosphine oxide (BCPPO) in pure water were determined by sodium hydroxide titration with phenolphthalein as indicator as discussed by the authors.
Abstract: The solubilities of dichlorophenylphosphine sulfide (DCPPS) and bis(4-carboxyphenyl)phenylphosphine oxide (BCPPO) in pure water were determined The concentration of the solution was determined by sodium hydroxide titration with phenolphthalein as indicator The synthesis and characterization of the compounds are described The solubilities of DCPPS were measured over the range 23 to 50 °C and the solubilities of BCPPO were measured over the range 23 to 75 °C with the uncertainty of 15% and 41% respectively

TL;DR: In this article, the same reaction sequence in toluene yields di(1H-inden-1-yl)phenylphosphine sulfide (3) as a mixture of (±) and two meso isomers.
Abstract: Dichlorophenylphosphine reacts with indenyllithium in tetrahydrofuran followed by sulfur to yield di(1H-inden-3-yl)phenylphosphine sulfide (2). The same reaction sequence in toluene yields di(1H-inden-1-yl)phenylphosphine sulfide (3) as a mixture of (±) and two meso isomers. The structures of (2) and (±)-(3) were determined [(2): C24H19PS, Mr 370·42, monoclinic, P21/n, a 14·329(4), b 7·0936(10), c 19·405(5) A, β 99·18(2)°, Z 4, R 0·060 for 2422 observed reflections; (3): C24H19PS, Mr 370·42, monoclinic, P21/n, a 9·521(5), b 16·223(8), c 12·930(6) A, β 107·41(3)°, Z 4, R 0·105 for 923 reflections].

TL;DR: In this paper, the reaction of 2,2,6,6-tetramethyl-3,4 heptadien-3-yl)phenylphosphinic acid (7), which undergoes Ag + -catalysed cyclization to 3,5-di-tert- butyl-2-phenyl-1,2-oxaphosphol-3 -ene 2-oxide (1e, 75-55% Z, 25-45%E).
Abstract: Reaction of 2,2,6,6-tetramethgl-4-heptyn-9-ol (5) with dichlorophenylphosphine leads to (2,2,6,-tetramethyl-3,4 heptadien-3-yl)phenylphosphinic acid (7), which undergoes Ag + -catalysed cyclization to 3,5-di-tert- butyl-2-phenyl-1,2-oxaphosphol-3-ene 2-oxide (1e, 75-55% Z, 25-45%E). Electrophilic bromination of 7 affords 1f, the 4-bromo derivative of 1e, as a 75% Z 55% E diastereomer mixture from which pure (Z)-1f can be isolated. Free radical allylic bromination of 1e and 1f leads to the corresponding 5-bromo derivatives 2e and 2f, each as the single diastereoisomer

Abstract: 2-Phenyl-1,2-oxaphospholane (1a), 2-phenyl-1,2-oxaphosphorinane (1b), 2-phenyl-1,2-thiaphospholane (1c), and 2-phenyl-1,2-thiaphosphorinane (1d) were prepared readily by the reaction of dichlorophenylphosphine with an ω-chloroalkanol or an ω-chloroalkanethiol followed by cyclization with the aid of lithium metal. Compounds 1b–d have been obtained for the first time.
