In an article, author is Ramagiri, Raj Kumar, once mentioned the application of 1439-36-7, Formula: https://www.ambeed.com/products/1439-36-7.html, Name is 1-(Triphenylphosphoranylidene)propan-2-one, molecular formula is C21H19OP, molecular weight is 318.35, MDL number is MFCD00008774, category is phthalazine. Now introduce a scientific discovery about this category.
An atom-efficient and environmentally friendly approach to the synthesis of 2,5-disubstituted-1,3,4-thidiazine derivatives has been developed. These compounds were synthesized by a reaction of 2-(2-bromoacetyl)benzofuran and thiocarbohydrazide with various aryl aldehydes, acetylacetones, and pthalic anhydrides in good yields. The advantages of this methodology are mild reaction conditions, easy workup procedure, clean reaction profile, shorter reaction time, and a wide range of substrate applicability. The structures of all synthesized compounds were confirmed from their analytical and spectral data.
