摘要：

Eight bridged diquaternary salts of methyl substituted 1,10‐phenanthrolines have been prepared. They are reduced in aqueous solution to radical cations at about the same potential as diquat by a one electron transfer which is largely reversed by air. in herbicidal tests they showed slight activity at a rate equivalent to 8 lb/acre. Their relatively poor phytotoxic properties are considered to be due to their large size which hinders their reaching the site of biological action of the bipyridylium herbicides.
