This review outlines the work to date concerning the mysteries of both the large optical effects and the bonding mechanisms involved with intercalation in heavy metal iodide systems. Such a system exhibits unusual shifts of the optical band edge to h

Hydrazine and methylated hydrazines were intercalated into thin films and crystalline powders of lead iodide. Interplanar spacing increased with increasing methylation. Weight gain and X-ray data provide estimates of the guest orientation. All three

Hydrazine and methylhydrazine were intercalated into polycrystalline thin films of lead iodide. Optical-band-edge shifts decreased with increasing methylation. This suggests a model whereby the polarization of the intercalate lowers and flattens the

The compound (2-chlorotetrafluoroallyl)manganese pentacarbonyl has been prepared, and its facile rearrangement to a propenyl isomer has been studied. The stereochemical results of the rearrangement are compared with those of cesium fluoride induced r

Nickel (II) forms complexes with methylhydrazine and ethylhydrazine in aqueous solution, but not with dialkylated hydrazines. These results are rationalized by considering steric factors in complexation.

Methanesulphonyl chloride reacts with hept-1-ene under the influence of short wave radiation to give β-chloroheptyl methyl sulphone. Methanedisulphonyl chloride, for which an improved preparation is described, and hept-1-ene react in the presence of
