PURPOSE: 1-Phthalimidoalkanediones of the formula I (where R is lower alkyl; R' is a substituent participating in no reaction of this invention, and when two R's are adjacent each other they may link together to form a ring; n is 0 or 1W4: and R4WR6 are OH when R1WR3 are H, or else R1 and R4, R2 and R5 or R6 represent a carbonyl group both together respectively. For example, 1-phthalimidohexane-2,5-dione may be cited.
