ADAMANTYL-CONTAINING CATALYTIC SYSTEM, METHOD FOR OBTAINING INTERMEDIATES FOR BIDENTATE LIGANDS OF SUCH SYSTEM, AND METHOD FOR ETHYLENE COMPOUND CARBONYLISATION IN PRESENCE OF CATALYTIC SYSTEM

摘要

FIELD: chemistry.;SUBSTANCE: invention claims catalytic system capable to catalyse non-substituted compounds of olephine series, the system obtained by combination of: (a) metal of VIB or VIIIB group or its compound; and (b) bidentate phosphine of the general formula (I): (Ad)_s(CR⁴R⁵R⁶)_TQ²-A-(K,D)Ar(E,Z)-B-Q¹(Ad)_u(CR¹R²R³)_v(I), where Ad is optionally substituted adamantyl radical linked to phosphor atom over any of its tertiary carbon atoms. In addition, invention claims method of obtaining this catalyst and method of carbonylisation of non-saturated ethylene series using this catalytic system.;EFFECT: high catalyst selectivity, reduced byproduct obtainment.;29 cl, 2 tbl, 10 ex
