Abstract:
1. A catalytic composition comprising a neutral metal-pair complex, comprising a first metal atom, M 1 , and a second metal atom, M 2 , having a through-space internuclear distance of at least 1.5 Angstroms and no more than 20 Angstroms; wherein said neutral metal-pair complex is according to formula I, wherein: L L L R R S S A a, b, h, k, m, and p are selected from 0 and 1; c equals 1; 1≦m+p≦2; the sum d +f+r+t=4, 5, or 6; and the sum e +g+s+u=4, 5, or 6; wherein at least one of R with the proviso that (i) when the sum d+f+r+t=4, (ii) when the sum d+f+r+t=5; (iii) when the sum d+f+r+t=6;
