Abstract
Катализаторът има формула в която r1, r2, r3, r6, r7, r8 независимо един от друг са алкилни групи, съдържащи от 1 до 15 въглеродни атома, арилни групи с 6 до 15 въглеродни атома, алкиларилни групи със 7 до 20 въглеродни атома, арилалкилни групи със 7 до 20 въглеродни атома, r4 и r5 независимо един от друг са н, алкилни групи с 1 до 15 въглеродни атома, арилни групи с 6 до 15 въглеродни атома, алкиларилни групи със 7 до 20 въглеродни атома, арилалкилни групи със 7 до 20 въглеродни атома, -с(о)оr', където r' е въглеводороден заместител с 1 до 15 въглеродни атома, -sо3м, където м е li, nа, к, nн+, nr''+, като r'' е въглеводороден заместител с 1 до 15 въглеродни атома, -rе бивалентен въглеводороден радикал, например алкандиилов, алкендиилов, циклоалкандиилов, бициклоалкандиилов, циклоалкендиилов, бициклоалкендиилов, арендиилов, арилалкандиилов, алкиларендиилов, с 1 до 20 въглеродни атома, 1,1'-фероцендиилов радикал, моноили дизаместен 1,1'-фероцендиилов радикал, при което като заместители се използват -с(о)оr' или sо3м, като r' и м имат посочените значения. Катализаторът се получава при взаимодействието на ni(о) съединения с бискетоилиди и третични фосфини в среда от полярни или неполярни разтворители или смеси от тях при температура от -20 до 800с. 13 претенцииThe catalyst has a formula in which r1, r2, r3, r6, r7, r8 are independently of one another alkyl groups containing from 1 to 15 carbon atoms, aryl groups of 6 to 15 carbon atoms, alkylaryl groups of 7 to 20 carbon atoms, arylalkyl groups of 7 to 20 carbon atoms, r4 and r5 independently of each other are n, alkyl groups of 1 to 15 carbon atoms, aryl groups of 6 to 15 carbon atoms, alkylaryl groups of 7 to 20 carbon atoms, arylalkyl groups of 7 to 20 carbon atoms, -c(o)or', where r' is a hydrocarbon substituent of 1 to 15 carbon atoms, -so3m, where m is li, na, k, nn+, nr''+, as r'' is a hydrocarbon substituent of 1 to 15 carbon atoms, -re is a bivalent hydrocarbon radical, e.g., alkanediyl, alkenediyl, cycloalkanediyl, bicycloalkanediyl, cycloalkenediyl, bicycloalkenediyl, arenediyl, arylalkanediyl, alkylarenediyl, of 1 to 20 carbon atoms, 1,1'-ferrocenediyl radical, mono or disubstituted 1,1'-ferrocenediyl radical, in which -c(o)or' or so3m are used as substituents, where r' and m have the indicated meanings. The catalyst is obtained by the interaction of ni(o) compounds with bisketoylides and tertiary phosphines in an environment of polar or non-polar solvents or their mixtures at a temperature from -20 to 800C. 13 claims
