Prolonged treatment of (1R)-(+)-camphor with 1,l -dimethylhydrazine gives (1R)-( +)-camphor dimethylhydrazone 3a which with LiBu, followed by PPh,CI, gives the corresponding compound 3c which has the Ph2P group in 3-exo ...

Pyrrole undergoes oxidative polymerization from acetonitrile solution at a metallic anode to form a dark coloured skin that adheres firmly to the metal surface. This simple electropolymerization step, when applied to pyrrole ...
