FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention relates to new P,N-bidentate ligands of the formula (I):
![](/patent/RU2239639C1/i/00000009.png)
wherein A represents sulfur atom (S) or NR wherein R represents (C1-C4)-alkyl; R1 and R2 represent hydrogen atom, (C1-C4)-alkyl or R1 and R2 can be cyclizated to form benzene ring; R3 and R4 represent (C1-C4)-alkyl or phenyl; R5 and R6 represent (C1-C4)-alkyl. Indicated compounds can be used as components of catalysts in reactions of amination, cross-coupling, hydroformylation, allyl alkylation and others.
EFFECT: improved preparing method.
