studies. The isocyanide derivatives are the least stable complexes, and the S-bound methionine oxide derivative is the more stable one. The complexes do not release CO gas to the headspace, but release CO2 instead. X-ray diffraction of crystals of the model protein Hen Egg White Lysozyme soaked with 6b (4UWN) and 8 (4UWV) shows the addition of RuII(CO)(H2O)4 at the His15 binding site. Soakings with
@ 3-(Activated ester)methyl-3-cephem 4-carboxylic acids are prepared by the direct reaction of a 3-hydroxymethyl-3-cephem-4-carboxylic acid with an activated-0-ester-methyl forming acylating agent, in the presence of a 4-(tertiary amino) pyridine catalyst and an acid-absorbing base, in a non-polar liquid solvent, at -78 to 30 C. Certain products of the reaction are novel.
