Although optimum conditions remainto be de-termined, the reduction can be carried out in
alcohol solution containing two to three equivalents of hydrazine hydrate and ca. 0.2 …

A new procedure has been developed for reduction of phenolic ethers to dihydro enol
ethers, suitable for cleavage to ß,-or,/9-unsaturated ketones. This method, using lithium in …

During a study of the preparation of unsymmetrical aliphatic secondary amines, a three-step
process for their preparation from ketones and ammonia has been developed. This method …

(1953).(3) In a formal sense an electronic archetype for these reactions may well be the
transformation of l, 3, 3-triraethyl-2-methyleneindoline into l, 3, 3-trimethyl-2-isopropylidene …

R* CO* NH* NH* SO, Ph+ Ph* SO, K+[R* CO* N: NH] __+ RCHO+ N, and the generality of

dissolved in 200 g. of chloroform was cooled to 10-12 and maintained at this temperature …

The reduction of cyclic y diketones with amalgamated zinc and hydrochloric acid has been
studied. While the eight-and seven-ring systems yield 1, 2-glycols, cyclohexane-1, 4-dione …

The ketone obtained in (2) was identified by comparison with cinnamylacetone prepared
from ethyl acetoacetate and cinnamyl chloride (Bergmann and Corte, J., 1935, 1363), and by …

Sir: Prompted by Thiele's early work1 on azodicar-boxylic acid, and other considerations, we
recently investigated the decomposition of this substance in the presence of olefinic …
