Kormachev, V. V. published the artcilePhosphorus-containing intermediates and dyes. IX. Syntheses based on aryldichloro- and diarylchlorophosphines, Formula: C15H15OP, the publication is Zhurnal Obshchei Khimii (1988), 58(4), 770-6, database is CAplus.
Bis(aminoaryl)alkylphosphine oxide intermediates for azo dyes were obtained in high yields by addition of alkyl halides to chlorodiarylphosphines, conversion of the crystalline dihalophosphorane intermediates to phosphine oxides with alcs., nitration of the phosphine oxides, and reduction of the nitro groups. The reaction of bis[2-(N-ethyl-N-phenylamino)ethyl] phenylphosphonite with EtI occurred under mild conditions only at the P atom to give 2-(N-ethyl-N-phenylamino)ethyl ethylphenylphosphinate. Azo coupling of the P-containing primary and tertiary aromatic amines gave new types of dyes with good dyeing properties.
