Steric hindrance was observed during the oxidation of 2,4,6-tri-tert-butylphenylphosphole to the P oxide and in the dimerization of this latter species to the corresponding phosphanorbornene derivative. Single-crystal X-ray analysis of the dimer revealed considerable steric crowding around the P ato

Thermally induced O Ar !S Ar migration in aryl thiocarbamates (1!2, Scheme 1) [1] is commonly referred to [2] as the Newman-Kwart rearrangement ("NKR") [3] and belongs to a group of rearrangements that generate Ar-S/N compounds from phenols. [4] Of these, only the NKR has been extensively utilized,
