"Oligomethylene-Bridged Vitamin B12 Dimers";
Angewandte Chemie - International Edition, 34 (2003), 1; 84 - 86.



English abstract:
The reaction of the highly nucleophilic CoI form of vitamin B12 with 1, -dibromo-n-alkanes (>=4) leads to oligomethylene-bridged B12 dimers in high yields. Use of 1,4-dibromobutane results in a dimer (shown schematically on the right), in which the two cobalamin moieties are tightly packed and coaxially linked through a tetramethylene chain, which is a synclinal conformation.

Keywords:
alkanediyl-bridged complexes ; cobalt compounds ; vitamin B12
