Abstract:
A process for making a catalyst product which comprises reacting dialkyltin oxide with an alcohol and the corresponding alkyl carbamate at a temperature in the range between about 160 to 190.degree. C. and at an autogenous pressure, wherein the catalyst product comprises dialkyltin dialkoxide in the range between about 50 to 100 mole % based on the tin species of the catalyst product.
Abstract:
Novel 2-chloro and 2-bromo derivatives of 1,5-iminosugars are disclosed, especially such derivatives of 1,5-dideoxy-1,5-imino-D-glucitol. These compounds are useful inhibitors of glucosidase enzymes and also are useful as antiviral agents and as intermediates for the synthesis of other enzyme inhibitors and antiviral compounds.

Abstract:
This invention is concerned with producing ethylene and/or 1,2-propylene glycol by the reaction of a non-cyclic oxymethylene compound formed by the hydration or acetalization of formaldehyde with a compound containing one or more of silicon, germanium and tin bonded therein which functions as an addend in a photochemically or thermally induced radical reaction, to form a 1,2-dioxyethylene containing compound, and cleaving such 1,2-dioxyethylene containing compound to form the glycol thereof.
Abstract:
