The santene has been formed from camphenilol or camphenilene by a pina 
rearrangement thus putting the santene formula of Semmler on a sound basis. _ 
The isocamphenilol described by Komppa and Hintikka in their previous work

with santenone (= Semmler’s 2-norcamphor). e 
For preparing camphenilene,’the authors heated a mixture of camphenilol 1 w 
sodium hydrogen sulphate for one hour in an oil bath up to 190 to 200°. The hyd 
carbon was removed from the reaction product by careful distillation, then was
