Claims
- 1. A catalyst complex of the formula:
- [NC--R--S--(R').sub.m --CN].[CuHal]
- in which R and R'are identical or different and represent alkylene having from 1 to 6 carbons in a straight chain or in a branched chain and which may contain an --O-- or --S-- bridge; m is 0 or 1; and Hal is selected from the group consisting of fluorine, chlorine, bromine and iodine.
- 2. A catalyst complex according to claim 1 wherein the sulfide is selected from the group consisting of bis-(.beta.-cyanoethyl ethoxy) sulfide, bis-(.beta.-cyanoisobutyl) sulfide, bis-(.beta.-cyanopropyl) sulfide and bis-(.beta.-cyanoethyl) sulfide.
- 3. A catalyst complex according to claim 2 wherein the sulfide is bis(.beta.-cyanoethyl) sulfide.
- 4. A catalyst complex according to claim 1 wherein (CuHal) is cuprous bromide.
- 5. A catalyst complex according to claim 1 wherein (CuHal) is cuprous chloride.
- 6. A catalyst complex according to claim 1 having the formula:
- [S(C.sub.2 H.sub.4 CN).sub.2 ].[CuCl]
- 7. A catalyst complex according to claim 1 having the formula:
- [S(C.sub.2 H.sub.4 CN).sub.2 ].[CuBr]
- 8. A catalyst complex according to claim 1 of the formula:
- [NC--R--S--(R').sub.m --CN].[CuHal]
- in which the sulfide is selected from bis-(.beta.-cyanoethyl ethoxy) sulfide, bis-(.beta.-cyanoisobutyl) sulfide, bis-(.beta.-cyanoethyl) sulfide and bis-(.beta.-cyanopropyl) sulfide; and (CuHal) is selected from the group consisting of cuprous bromide and cuprous chloride.
- 9. A process for the preparation of a catalyst complex claimed in claim 1 consisting of mixing equimolar quantities of the compounds NC--R--S--(R').sub.m --CN and (CuHal) wherein R, R', m and Hal are defined as in claim 1.
