Abstract:
Carbohydrate research remains one of the most exciting endeavors in the field of organic chemistry. The importance of carbohydrates needs little elaboration. Quite literally, without glucose, cellulose, and starch, the necessities of life such as food, clothing, and shelter would be missing. In our laboratory, we have for some time been interested in one particular class of carbohydrate derivatives - the aldohexopyranosyl cyanides.

Abstract:
Chemistry in the interstellar medium is very different from the processes which take place in terrestrial settings. Environments such as circumstellar envelopes, molecular clouds, and comets contain diverse and complex chemical networks. The low temperatures (10-50 K) and densities (1-10⁶ cm⁻³) allow normally unstable molecules to exist in significant quantities. At these temperatures, the rotational energy levels of molecules are populated, and thus these species can be detected by millimeter-wave radio astronomy.

The anion binding properties of (3.1) and (3.2) were investigated and both were shown to bind one equivalent of cyanide.

A method for the simultaneous determination of total gold and available cyanide in gold cyanidation solutions has been investigated. Total gold and available cyanide in cyanidation solutions are determined by ion exchange chromatography-HPLC under slightly acidic conditions.

The nickel(D)-cyanide complex is not strong enough to dissociate the very strong dicyanoaurate(I). Anion exchange is used for the

The oxidation of several transition metal cyanides by illuminated colloidal titanium dioxide has been studied with attention to end products and rate of reaction. Tetracyanozinc, a weak complex, and ferricyanide, a stable complex were the primary focus. The rate of complex dissociation of ferricyanide was found to depend on pH. The rate of oxidation of cyanide was found to be the same both complexed and as alkali cyanide. Although the precipitation of metal oxide onto the catalyst occurred, there was no evidence that it interfered in the oxidation of cyanide.
