## Previous work of Hansson and Rasmusson (1) has shown that low concentrations (lO-' M) of ascorbic acid enhance the rate of purified milk acid phosphatase catalyzed hydrolysis of phenyl phosphate by 500/o, and that higher concentrations of ascorbic acid (lo-'M) are completely inhibitory. It was

## Abstract The ^13^C‐NMR chemical shifts of dicyanocobyrinic acid heptamethyl ester (**1**), an important corrinoid model compound, are correlated with those of some derivatives. Isotope effects on the ^13^C chemical shifts (over two to four bonds) are observed for the 10‐deuterio and the 10,13‐di
