I. 11. of the reaction was 3-hydroxy-1: 1-dimethylhexahydrobenzene (11), which may be described as the limit reduction product of the chloroketone, The main object of the present investigation was to find reducing agents, less powerful than sodium in moist ethereal solution, which would be discriminating in their action; so that it might be possible to prepare from cliloroketodimethyltetrahydrobenzene, first, a ketodimethylletrahydrobenzene, ...
