Heteroaryl-eridivisie and method of production thereof

 

The invention relates to new heteroaryl-alldifferent formulas (I) and (II) for compounds of formula (I) A=S if V=C; A=N, if B=N, R₁is hydrogen or C₁-C₄alkyl, R₂-R₅-phenyl, R₆and R₇is hydrogen, n=0 or 1, R₈-R₁₁is hydrogen; compounds of f-crystals (II) A=N, if I=S, R₁=C₁-C₄alkyl, A=C, if B= N, R₁is hydrogen; A=N if I=N, R₁=0; And=O, if=S, R₁=0, R₂-R₅- phenyl, R₈-R₁₁is hydrogen or C₁-C₄alkyl. Compounds of formula (I) and (II) can be used to obtain transition metal complexes, which catalyze the reaction, amination, hydrogenation or hydroformylation. 2 S. p. f-crystals, 1 PL.

Claims

1. Heteroaryl-eridivisie General formulas I and II

and

where compounds of formula (I)

A=S if I=S;

A=N if=N;

R₁is hydrogen or C₁-C₄alkyl;

R₂-R₅is phenyl;

R₆and R₇is hydrogen;

alkyl;

A=C, if=N, R₁= hydrogen;

A=N, if I=N, R₁=0;

A=On, if=S, R₁=O,

2. The method of obtaining compounds of General formula (I) or (II) under item 1, which consists in the fact that the compound of General formula (III) or (IV)

where R₁, R₆-R₁₁have the values listed in paragraph 1, is subjected to the interaction with butyllithium with subsequent treatment of the resulting product with diphenylchlorophosphine.
