FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to new heteroaryl-aryldiphosphines of formulas (I) and (II) wherein for compounds of the formula (I): A means sulfur atom if B means carbon atom; A means nitrogen atom if B means nitrogen atom; R1 means hydrogen atom or C1-C4-alkyl; R2-R5 means phenyl; R6 and R7 means hydrogen atom; n = 0 or 1; R8-R11 mean hydrogen atom; for compounds of the formula (II): A means nitrogen atom if B means carbon atom R1 means C1-C4-alkyl; A means carbon atom if B means nitrogen atom; R1 means hydrogen atom; A means nitrogen atom if B means nitrogen atom; R1 means oxygen atom; A means oxygen atom if B means carbon atom; R1 means oxygen atom; R2-R5 mean phenyl; R8-R11 means hydrogen atom or C1-C4- alkyl. Compounds of formulas (I) and (II) can be used for preparing transient metals complexes that catalyze amination, hydrogenation or hydroformylation reactions. EFFECT: improved preparing method. 2 cl, 1 tbl, 7 ex |
