 Title    Reduction of Indolic Imides with Sodium Borohydride ATTA-UR-RAHMAN and NIGHAT WAHEED  
 Abstract    Reduction The reduction of imides with sodium boro-hydride affords ring cleaved products instead of the corresponding carbinol lactams sug-gested previously.

 Title    Synthese und Bindungsverhältnisse von 1-Dimethylaminothiabenzol-l-oxiden Synthesis and Bonding Properties of 1-Dimethylaminothiabenzene-l-oxides  
 Abstract    The 1-dimethylaminothiabenzene-l-oxides 5a—d are obtained by the reaction of the 2-propy-nones 2a—d with methyl-dimethylamino-oxosulfonio methanide 3 and subsequent treatment of the mixture with f-BuOK. The bonding properties of 5a—d are discussed by comparison of their IR, 'H and 13 C NMR data with those of the already known 1-methylthiabenzene-l-oxides 6a—d.
