PHOSPHORVERBINDUNGEN UNGEWOEHNLICHER KOORDINATION,6. ABFANGVERSUCHE VON PHENYL-THIOXO- UND PHENYL-SELENOXOPHOSPHAN MIT PROTISCHEN NUKLEOPHILEN

The thioxophosphole 6 undergoes Diels-Alder reaction with the triazolindiones 7a and b to the adducts 8a and b.Analogously 11a and b are formed from the selenoxophosphole 9 and the maleic acid derivatives 10a and b.The triazolindion reactions of 6, 9 and also of 12 suffer considerably under the presence of water.Apart from elemental sulfur and selenium on the one hand phosphole oxides (15) such as secondary products and triazolidindiones (19) on the other hand are formed.Thermolysis of the Diels-Alder adducts 8a and b in toluene proceeds under cycloreversion to 20 and phenyl thioxophosphan (21) which is trapped by alcohols (22,24) under production of phosphinothioates (23,25).Phenyl selenoxophosphane (27) is generated by photochemical decomposition of 11a and b.The trapping reaction with methanol leads to the phosphinoselenoate 29 which is transformed into the phosphonoselenoate 28 under the conditions of the photolysis.
