310 ACTION OF OHCANO-MAGNKSirM COMPOUNDS, ETC. — WALLACE. 



The investigation of the compound having the empirical 

 formula CeH^O obtained from the action of ethyl- 

 magnesium bromide on quinone is proceeding ; as indicated 

 in the experimental part, similar and probably identical, com- 

 pounds were obtained from methylmagnesium iodide and 

 phenylmagnesium bromide, but until further study has shown 

 the nature of this substance, nothing definite can be stated 

 of the part it plays with regard to the reaction. 



No pinacone has been obtained, and no quinol of the 

 structure obtained by Bamberger and Blangey. 



These experiments were carried out in the laboratories of 

 Dalhousie University and were suggested by Professor E. 

 Mackay, and I wish, in conclusion, to thank him for the sug- 

 gestions, helpful criticisms and kindness offered during the 

 progress of the work.
