Abstract

Abstract: Hexahydropyrimidines N, N-bridged by a chain of n methylene groups (l,(n+ 2)- diazabicyclo [n. 3. llalkanes) adopt out, out (axia1, axial) structures for n= 2, 3, and 4. When n= 5, the photoelectron spectrum shows evidence of the presence of some of the out, in (axia1, equatorial) isomer in the gas phase, although none can be found in solution. When n= 6, the compound is apparently entirely outin in the gas phase but exists as a mixture of ...
