Does anyone have a good lab prep procedure for potassium phtalimide handy (from phtalimide and KOH)? |

Ive never heard of this compound before? An alkalai imide? Are you referring to a C6H4(CO)2NK species? I mean literally the potassium bonded to the nitrogen in place of the hydrogen of the imide? I didn't know such a species could exist. PrimoPyro Vivent Longtemps la Ruche! STRIKE For President! |

Or does he want to hydrolyze it, getting rid of the nitrogen and producing the potassium salt of the corresponding lactone (phthalide). There is a procedure in Vogel for this (sodium salt not potassium). He does not isolate the salt though, instead it is immediately treated with HCl to form the lactone. |

Vogel's 3rd Ed states that if the alternative Gabriel synthesis using phthalimide and potassium carbonate isn't feasible, than one may prepare potassium phthalimide from a solution of phthalimide in absolute ethanol and potassium hydroxide in 75% ethanol |
