Fig. 9 Influence of catalyst formal potential ( °) on log /ci for reaction of Co L with DBCH in a bicontinuous microemulsion (A) of DDAB/water/dodecane (21/39/40) and in dimethylformamide ( ) for dissolved catalysts vitamin B12, Co(salen), cobalt phthalocyaninetetrasulfonate (CoPCTS), cobalt tetraphenylporphyrin (CoTPP), and cobalt octaethylporphyrin (CoOEP). Points from reactions in the microemulsion (A) represent apparent k values for 0.4, 0.5,1.0, and 2.0 mM catalyst in order of decreasing log fci.

Use of the kinetic advantage method thus points clearly to the occurrence of chemical catalysis with the low-valent metalloporphyrins. This is confirmed by repeating, with iron(I) octaethylporphyrin and cobalt (I) etioporphyrin, the stereochemical experiments carried out earlier with the anion radical of 1,4-diacetylbenzene. Complete stereospecificity is observed in both cases The meso isomer of 4,5-dibromooctane is converted totally into the c/.v-olcfin the d,l isomer is converted totally into the trans-olefin. The reaction again exhibits a clear antiperiplanar preference.
