TL;DR: A new diamine, bis(4-((4-aminophenyl)thio)phenyl)(phenyl)phosphine oxide (BATPO), containing phosphine oxide and thioether bonds was prepared via the Grignard reaction to dichlorophenylphosphines oxide with 4-fluorophenylmagnesium bromide, followed by an aromatic substitution reaction with 4aminothiophenol as discussed by the authors.

TL;DR: Dichlorophenylphosphine and alcohols exhibited unexpected reactivity towards C 60 and a possible reaction mechanism involving the formation of P(III)–OH in situ was proposed to explain the experimental results.
Abstract: Hydrophosphorylated fullerene derivatives were readily prepared in one step by treating C 60 with Ph 3 – n PCl n ( n = 1–3) and ROH (R = H, alkyl). The one-pot reaction could be performed under mild conditions with moderate to good yields. Dichlorophenylphosphine and alcohols exhibited unexpected reactivity towards C 60 . A possible reaction mechanism involving the formation of P(III)–OH in situ was proposed to explain the experimental results.

TL;DR: In this paper, a 2]-(2-dimethylaminophenyl)(phenyl)phosphino]-N,N-dimethylaniline copper iodide complex and a synthesis method and the application thereof are presented.
Abstract: The invention relates to a 2-[(2-dimethylaminophenyl)(phenyl)phosphino]-N,N-dimethylaniline copper iodide complex and a synthesis method and the application thereof. The synthesis method comprises thefollowing steps: firstly, enabling 2-bromoaniline and methyl iodide to be in a substitution reaction to produce N,N-dimethyl-2-bromoaniline, and then enabling the N,N-dimethyl-2-bromoaniline and n-butyllithium to be in reaction in a tetrahydrofuran solution to produce aryl lithium; continuing to enable the aryl lithium and dichlorophenylphosphine to be in reaction to produce a ligand 2-[(2-dimethylaminophenyl)(phenyl)phosphino]-N,N-dimethylaniline (ppda), and finally enabling the ppda and cuprous iodide to be in reaction in a dichloromethane solution to obtain a target product. When the synthesis method is used for synthesizing the target product, the yield is high and reaches 72%, and the synthesis method is simple and easy to operate; in addition, the target product has a dual-emissioncharacteristic, can be used as a light-emitting material for assembling an OLED, and has a good application prospect.

TL;DR: In this article, a method was developed for the synthesis of 1,5-dialkyl(cycloalkyl,phenyl)-2-phenyl-6-oxa-2-phosphabicyclo[3.1]hexane 2-oxides from alkynes, involving the epoxidation of unsaturated cyclic organophosphorus compounds with m-chloroperbenzoic acid.
Abstract: A method was developed for the synthesis of 1,5-dialkyl(cycloalkyl,phenyl)-2-phenyl-6-oxa-2-phosphabicyclo[3.1.0]hexane 2-oxides from alkynes, involving the epoxidation of unsaturated cyclic organophosphorus compounds with m-chloroperbenzoic acid. The organophosphorus compounds were obtained by a reaction sequence consisting of catalytic cycloalumination of symmetrical acetylenes with triethylaluminum in the presence of bis(cyclopentadienyl)zirconium(IV) dichloride catalyst leading to the formation of 2,3-disubstituted aluminacyclopent-2-enes and in situ reaction of the latter with dichlorophenylphosphine.
