The Action of Organo-Magnesium Compounds on Quinone. 

 — By Curtis C. Wallace.* 



Read Maj' 23rd, 1910. 



It is generally known that quinone has properties common 

 to both a diketone and a peroxide, but it differs, however, from 

 the former in being a powerful oxidizing reagent and from 

 the latter in forming an oximide compound with hydroxyla- 

 mine. It is also known that diketone^ with Grignard's 

 reagents undergoes the pinacone condensation yielding the 

 corresponding pinacone. Further, Bamberger and Blangey^ 

 obtained a quinol of the structure

with methyl magnesium iodide from toluquinone and xylo- 

 quinone, but were unable to get the same from quinone. In
