Zusammenfassung: 
Reactions of alkyl iodides RI (R = CHI2, CH2I or tert-Butyl) with P(4)E(3) (E = S or Se) under the influence of light resulted in cleavage of the basal P-3 ring. beta-P(4)E(3)(I)R was formed initially, then it rearranged to the more stable alpha-P(4)E(3)(I)R structure. P-31 NMR data of these products were measured and discussed, along with Se-77 data for alpha- and beta-P-4 (SeSe2)-Se-77-(I)CHI2. On reaction of P4S3 with tert-butyl iodide in CS2 or with sec-butyl iodide or iso-propyl iodide in dioxane, the new type of compounds P(5)S(2)R was observed. In this a sulfur bridge of P4S3 replaced by a P-R group. P-31-NMR data for these compounds are reported.
