## Abstract The mass spectra of 20 1,3‐dithianes were studied. The fragmentation patterns including the loss of 74 u and 107 u and clearage of the substituent at C‐2 depended strongly on the nature of the substituents at that position. 2,2‐Diphenyl‐1,3‐dithiane undergoes an atypical fragmentation i

Abstract
The full set of NMR spectral parameters (^1^H, ^13^C, ^31^P) are reported for 2‐phenyl‐1,3,2‐dithiaphosphorinane and 2‐phenyl‐1,3‐dithiane. The stereochemical dependence of the coupling constants is discussed.

## Abstract The configuration of some 1,4‐dihydroxy‐2,3‐dialkylcyclopentanes is assigned on the base of their ^1^H‐NMR spectral parameters. The interaction of the hydroxyl group with some side chains is discussed. It is shown that the magnitude of the ^1^H‐NMR spectral parameters of specific hydrog
