N-Arylnitrilium salts 1 react with nucleophilic alkenes 2 to afford 3,4-dihydroquinolinium salts3 , which can be transformed into the free bases with aqueous sodium hydroxide. Dehydrogenation of the 3,4-dihydroquinolinium salts 3 with 2,3-dichloro-5,6-dicyano-p-benzoquinone furnishes quinolinium salts 7. If the intermediate carbenium ion A formed by electrophilic attack of 1 on the alkene 2 is conjugatively...
A magnesium complex of aminomethyl(hydrogen)phosphonate ([O 3 PCH 2 NH 3 ] - ; AMPH - ), the monoanion of aminomethylphosphonic acid (AMPH 2 ), has been prepared from the free acid and Mg(OH) 2 in water. According to an X-ray structure analysis it has to be formulated as [Mg(AMPH) 2 (H 2 O) 2 ] 2H 2 O containing...
