Birch reduction of benzenesulfonamide and benzenephosphonic acid
… such as alcohol to affect partial reduction of aromatic compounds, commonly known as the BIrch reduction, has proven to be a synthetic procedure of great utility. (1) The flexibility and usefulness of this reaction has attracted increasing attention in recent times, primarily by BIrch (1,2). The …

PART I PREPARATION OF NOVEL LACTONES AND THEIR PRECURSORS DERIVED FROM METHYL SALICYLATE PART II NUCLEOPHILIC AROMATIC SUBSTITUTION IN A DINITROSALICYLIC LACTONE WITH RING OPENING AND ELIMINATION VIA MEISENHEIMER INTERMEDIATES
… described. The influence of substituents on the aromatic nucleus in affecting ring closure reactions was examined. Experimental results show that ring closure is enhanced when nitro groups are incorporated in the aromatic ring. Investigations were conducted in the preparation of compounds …
