Abstract: Symmetrical or asymmetrical bis-phosphino, bis-arsino or phosphino-arsino compounds are produced by reacting a dihalo-organic compound with two benzyl-diorganyl-phosphine or -arsine compounds which may or may not be identical and then hydrogenating the product. A process for the production of compounds of formula (V) involves reaction of a compound of formula (I) with a dihalo compound (II) and a compound of formula (III) followed by hydrogenation. Hal-X-Hal (II) R R E-X-ER R (V) E = phosphorus or arsenic; X = a bridging group with 1-10 atoms between the atoms of E; R , R , R , R = 1-20C alkyl, 3-10C cycloalkyl, aryl or heteroaryl with up to 4 condensed rings, or 7-20C aralkyl (all optionally substituted), or R , R and/or R , R together may form 2-20C alkylene, arylene or heteroarylene groups with up to 4 condensed rings, or 7-20C aralkylene (all optionally substituted; R -R = H, hydroxyl, halogen, acyl, CHO, 1-12C alkyl or 6-12C aryl, with the proviso that R and R are not both OH; Hal = F, Cl, Br or I; R -R = as defined for R -R .

Abstract: A process for the production of bisphosphino- and bisarsino-compounds comprises reaction of an aryl phosphorous or arsenic containing compound with a dihalogenated compound. A process for the production of compounds of formula (5) comprises reaction of a compound of formula (1) with a dihalo compound of formula (2) and a compound of formula (3) followed by hydrogenation. Hal - X - Hal (2) R R - E - X - E - R - R (5) E = P, As; X = a divalent bridging group whereby are separated by 1-10 atoms; R , R , R , R =1-20C alkyl, 3-10C (cycloalkyl, aryl or heteroaryl having up to 4 condensed aromatic rings or 7-20C aralkyl, optionally substituted or R , R and/or R , R together are 2-20C alkylene, arylene or heteroarylene with up to 4 aromatic rings, 7-20C aralalkylene, optionally substituted; R , R R , R , R , R = H, OH, halogen, acyl, CHO, 1-12C alkyl, 6-12C aryl whereby R and R are not both OH; Hal = F, Cl, Br or I.

Abstract: Production of bis(phosphino/arsino-) compounds comprises reaction of an alkylene sulfate with alkali metal phosphine or arsine compounds. A process for the production of compounds of formula R R E-CR R -(CH2)nCR R -ER R (1) comprises reaction of an alkylene sulfate of formula (2) with an alkali compound of formula R R EM (3) and an alkali compound of formula R R EM (4); R -R = H, OH, halogen, acyl, CHO, 1-12C alkyl, 6-12C aryl, whereby R and R or R and R may not be simultaneously OH; R -R = 1-20C alkyl, 3-10C cycloalkyl, aryl or heteroaryl having up to 4 condensed aromatic rings or 7-20C aralkyl, (un)substituted; E = P, As, N; R E, R E = S; n = 0-6; M = Li, Na or K.
