... Second, for carbonylrhodium(I) complexes, (NNN)Rh(CO), substitution at the para-aryl positions predictably modulates the electronic properties and chemical reactivity. Oxidative addition reactions of the (NNN)Rh(CO) with iodoalkanes proceed about three orders of magnitude faster than those reported ...

Why does nature use zinc–a personal view†
... the metal zinc. In one of the early reviews on its biochemistry1 Vallee noted that it occurs in all six groups of the IUBMB enzyme classification. The number of enzymes known to contain zinc in the active center now exceeds 1000.2 In mid 2007 the Brookhaven protein data bank lists some 40 000 structu ...
