Phthalazine and 1(2H)‐phthalazinone undergo 1,2‐addition of organolithium compounds to C = N to give, following hydrolysis, 1 ‐ substituted ‐ 1,2 ‐ dihydrophthalazines and 4‐substituted‐3,4‐dihydro‐1(2H)‐phthalazinones respectively. These dihydro‐derivatives may be easily autoxidized to the corresponding 1‐substituted phthalazines and 4‐substituted‐1(2H)‐phthalazinones.
