This compound resembles camphor and menthol only in odor and volatility. Reactions are those you'd expect, with the qualification t h a t some can proceed to yield heterocyclic derivatives.

By offering you this number, we save you the trouble of reacting diketene with dimethylamine. People seem to be using the derivative for the syn­ thesis of mordant acid dyes and insecticides. Can other uses occur to you?

The symmetry and high degree of substitution of this lineal descendant of B14 impart unusual ther­ mal and hydrolytic stability to its diesters. They could be of more than passing interest as plasticizers and lubricants.

Resin chemists tell us this ether-amine is an efficient emulsifying agent for wax-polyethylene systems. A review of the literature suggests other uses: tetraazoporphin type dyestuffs, oral anti-diabetic agents, detergent preparation, synergistic agent for gaso­ line inhibitors, and herbicides. Does one of these match your product interest?

Thiol esters are obtained in the base- or acidcatalyzed reaction of this lactone with mercaptans. Reaction in the presence of a free radical catalyst produces intermediates which decarboxylate to give alkyl (l-isopropyl-2-methylpropenyl) sulfides.
