34 OPTICAL ACTIVATION 15V MEANS OF CATALYSTS. CREIGHTON 



4. By means of ilie stereochemical specific catalytic 

 influence of optically active bases, optically active hrom- 

 campliors, as well as optically active hromcatnplior-carhoxylic 

 acids, have been prepared from inactive hromcamplior-car- 

 boxyhc acid. 



5. Ill conclusion the specificity of catalysts has been 

 discussed.
