The oxidation of elemental phosphorus (P4) by elemental sulfur (S4) has been studied by a combination of 31P nmr and Raman spectroscopic techniques. At temperatures below the auto-ignition temperature, a molten mixture of the elements gives rise to a complex mixture of products which are dominated by phosphorus sulfides which have a high S/P4 ratio. Both the rate at which the products are formed and their distribution support the formation of a reactive P4S8 intermediate which then cascades through a series of reactions, incorporating the sulfur atoms into the phosphorus cage. Two new phosphorus sulfides (of composition P4S6 and P4S8) have been identified in these product mixtures.

The preparation of bicyclo [2.2.0]hex- 1(4)-ene ( 1 ) via ring expansion of a cyclopropylcarbene or the dehalogenation of 1-bromo-4-chlorobicyclo[2.2.0]hexane is described. It is one of the most reactive of the alkenes which may be observed at room temperature. Its reactions, including dimerization and cycloaddition reactions, are described. The latter lead to convenient preparations of [m.2.2]propellanes. The vibrational spectrum was examined via matrix isolation and ab initia MO calculations.
