In a study of the reaetion between alkyl halides and the electrogenerated naphthalene radical anion, Sease and Reed [297] observed that only alkyl chlorides, such as 1-chloro-hexane and 6-chloro-l-hexene, are catalytically reduced 1-chlorohexane gives only n-hex-ane, whereas 6-chloro-l-hexene affords methylcyclopentane and 1-hexene. In an earlier paper [296], the reactions of 1-bromo- and 1-chlorobutane with the electrogenerated radical anions of rmn -stilbene and anthracene in DMSO were examined. Britton and Fry [298] elucidated the kinetics of the electron-transfer reaction between 1-chlorooctane and the phenanthrene radieal anion in DMF. 

Ionic chlorination of alkanes.6 Alkanes are readily chlorinated by sulfuryl chloride in sulfolane (I, 1144-1145 2, 402-403). Thus adamantane (1) is converted almost exclusively into 1-chloroadamantane (2). Norbomane is converted under these conditions exclusively into 2-cxo-chloronorbornanc. -Hexane is converted into 1-chloro-hexane (20%), 2-chlorohexane (56%), and 3-chlorohexane (24%). The chlorination proceeds by an ionic mechanism. 

Intramolecular Cyclization Reactions.—Base-induced 1,3-eliminations continue to provide a useful route to cyclopropanes. The dehydrochlorination of 5-chloro-hexan-2-one by sodium hydroxide has been re-examined, and is now believed to yield the corresponding cis- and trons-cyclopropanes in a ratio of 5 95. ... 

In British practice the locant (or locants) is placed immediately before the syllable that it qualifies (see p. 35), as in hexan-3-one, hexane-2,3-dione, 1-chloro-hexan-3-one, hex-3-en-l-yne, pyrazol-3-yl, carbazole-2-carboxylic acid. In USA, one locant (or one set of locants) for a suffix is placed in front of the stem name, as in 3-hexanone, 2,3-hexanedione, l-chloro-3-hexanone, 3-hexene, 3-pyrazolyl but only one numeral (or set of numerals) is so placed any others precede the syUable that they qualify, 3-hexen-l-yne, 3-cyclohexen-l-one (the 1 maybe omitted in the second name, giving 3-cyclohexenone, where the 3 refers to the unsaturation en ). There are, however, many cases where parent names carry locants in front of them, e.g., m-dioxan, 1,7-naphthyridine (where the heteroatoms in the ring are cited by the locants 1,7 or m) in such cases the additional locants for suffixes are all placed after the parent name, as in m-dioxan-4-carboxylic or l,7-naphthyridin-2(lfl )-one. The tendency in Chemical Abstracts is to place the locants after the parent name whenever ambiguity might arise it is matched by a tendency in Great Britain to place one numeral in front of the parent name when no ambiguity can arise. A compromise seems to be working itself out unofficially.
