Preparation and characterization of 2,3-dihydro-2,3 bis (methylene) furan

2,3-dihydro-2,3 bis (methylene) furan and its 4-methyl derivative have been prepared by flash vacuum thermolysis and characterized by mass spectrometry and chemical trapping.     

Synthesis of (2,3-diphenyl)pyrazinotribenzoporphyrazine

By the method of template cyclotetramerization magnesium(II) (2,3-diphenyl)pyrazinotribenzoporphyrazinate was synthesized, and it was converted into (2,3-diphenyl)pyrazinotribenzoporphyrazine. (2,3-Diphenyl)-pyrazinotribenzoporphyrazine and (2-phenyl)imidazolotribenzoporphyrazine were synthesized from 5,7-diphenyl-1,4-diazepinotribenzoporphyrazine by vacuum sublimation.
