Electric Literature of 1608-26-0. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 1608-26-0, Name is Tris(dimethylamino)phosphine
. In a document type is Article, introducing its new discovery.
Photolysis of the pyridinophane N-oxides 3a-e provides the pyrrolophanones 5a-e.In addition, the 2H-azirines 6b-e and the furans 7a, 7b and 7e can be isolated as photoproducts of 3.These heterocycles have not been observed before during irradiation of pyridine N-oxides.Spectroscopic data of 5 and 6 are discussed indicating special structural properties of some of these compounds.Azirines 6 are stable under irradiation conditions.Thermolysis of 6b and 6c at 80 deg C gives the pyrroles 5b and 5c without polymerisation. 5e is easily reduced to give the pyrrolophane 8.Tris(dimethylamino)phosphane (TDP) reacts with 6c to give the phosphonium salt 14 in high yield.The role of the novel products during photoreactions of 3 is discussed. – Key Words: 2H-Azirines / Pyridine 1-oxides / (2,5)Pyrrolophanes
