- Water-soluble three (meta-sulfonate phenyl) phosphine preparation method
-
The invention relates to a preparation method of water-soluble tri(m-sulfonate phenyl)phosphine (TPPTS). The preparation method comprises the following steps of: adding sodium metaborate which is 1.5-20wt% of total reactants into 100% concentrated sulfuri

- PHOSPHINES SULFONEES ASYMETRIQUES V. CINETIQUE DE SULFONATION DES PHOSPHINES
-
The sulfonation of 1,2-, 1,3- and 1,4-diphosphines (dppe, dppp, dppb) is studied.It is shown that the sulfonation is faster for 1,4-diphophines than for 1,3- and 1,2-diphosphines.The conditions affording the tetrasulfonation are described, and also those allowing the obtention of a mixture containing large amounts of disulfonated diphosphines.This study is extended to chiral diphosphines (Cyclobutanediop, BDPP, Chiraphos).
