Abstract

The C  O stretching frequencies of twenty‐six cis‐5,6‐polymethylene‐2,3,5,6‐tetrahydro‐1,3‐oxazinone derivatives were measured in tetrachloromethane and in chloroform and correlated with the substituent constants X+(R) in the sense of the modified and extended Seth‐Paul Van Duyse equation. The influence of the fused hydrocarbon ring on the C  O stretching frequency and on the transmission of substituent effects through the six‐membered heterocyclic ring is discussed and compared with that in the previously investigated 5,6‐polymethylenepyrimidin‐4(3H)‐ones and cis‐5,6‐dihydropyrimidin‐4(3H)‐ones.
