An approach to pyrazoline-fused chlorins by dipolar [3 + 2]-cycloaddition of iminonitriles to Meso-Tetrakis(pentafluorophenyl)porphyrin: Synthesis of new PDT photosensitizers

Meso-Tetrakis(pentafluorophenyl)porphyrin reacts at higher temperature with unstable iminonitriles (RC≡N+-N--Ar), affording pyrazoline-fused chlorins, according to dipolar [3 + 2]-cycloaddition pathway. The respective iminonitriles were in situ generated from the corresponding functionalized α-halogenohydrazine derivatives by 1,3-elimination of HX in the presence of base (NEt3, DABCO). This method allows synthesis of very attractive moieties which may be of potential use as sensitizers in photodynamic therapy (PDT).

The reaction of 6,7-dihydrothieno[3,2-c]pyridine derivatives with 1,3-dipoles, such as a nitrile oxides or nitrile imines, gave novel fused heterocycles. The Staudinger reaction of the starting material was also studied. This reaction was stereoselective

A new and convenient method is described for the synthesis of hydrazonyl halides. Hydrazones on treatment with N-chlorosuccinimide-dimethyl sulfide complex result in the formation of the corresponding hydrazonyl chlorides in good yields. Similarly, treatment of hydrazones with N-bromosuccinimide-dimethyl sulfide complex gives the corresponding hydrazonyl bromide under extremely mild conditions.
1,3-Dipolar Cycloadditions of 2-Ethoxy- and 2-(Ethylthio)-1-azetines with Nitrile Oxides, Nitrile Ylides and Nitrilimines: An Unexpected 1,2,4-Triazole Formation.

2-Ethoxy- and 2-(ethylthio)-1-azetines readily undergo 1,3-dipolar cycloadditions with nitrile oxides and nitrile ylides to give stable 4,5-bicyclic cycloadducts.With nitrilimines, however, the expected 1,3-dipolar cycloadducts and/or unexpected ring-open

Certain benzoyl chloride phenylhydrazones have been found to be active against insects and mites. The benzoyl ring and the phenylhydrazone ring can be substituted with a halogen atom, a nitro group, or an alkyl group of from 1 to 6 carbon atoms, inclusive

Certain benzoyl chloride phenylhydrazones have been found to be active against insects and mites, and they have also been found to be effective, broad-spectrum anthelmintics for suppressing parasitic worms in animals, particularly sheep. The benzoyl ring
