From a comparison of β-effects given by methyl substituents in tricarbonyldieneiron complexes with those of the corresponding uncomplexed 1,3-dienes, it is concluded that bonding to iron results in a change in p-bond orders of the ligand. This change is consistent with the structure (1) making an important contribution to bonding in these complexes.

Carbon-13 and proton chemical shifts have been measured for several monosubstituted isothiazoles. Substituent effects upon these chemical shifts are compared with those observed for monosubstituted benzenes, pyridines, and thiophenes. In general the observed substituent effects in the isothiazoles and thiophenes closely parallel one another. Correlations between the observed carbon-13 Chemical shifts and CNDO/2 calculated charge densities are examined.
