Abstract:
A new reaction of elemental phosphorus (P4) with elemental sulfur and 1,3-propylene glycol in the presence of different amines has been investigated. Ammonium salts of O,O'- alkylenedithiophosphoric acids have been observed as main products of the reaction. Octathiotetraphosphetane ammonium salts were formed as minor products. The reaction is characterized by a complete conversion of white phosphorus and is not accompanied by the release of hydrogen sulfide. The crystal structure features's of diethylammonium salt of O,O'-propylenedithiophosphoric acid were determined using single crystal X-ray diffraction. Piperidinium salt of octathiotetraphosphetane in DMSO and DMF solutions possess significant antifungal activity against Candida albicans.

Strong bases like NaOH or KOH deprotonate the phthalimide to form the corresponding anion, which acts as a nucleophile. Further, the anion attacks an...
Preparation of Amides
The DCC-promoted synthesis of amides begins with the protonation of DCC by carboxylic acid. The protonation makes it a better acceptor. Next, the addition of carboxylate to the protonated carbodiimide gives a reactive acylating agent.
Subsequently, the amine acts as a nucleophile that attacks the acylating agent to form a tetrahedral intermediate. In the...
