In the title compound, C 20 H 24 N 2 O 4 , the quinoxalinediyl bridging group separates two -diketone groups, which are found to be in a pseudo-trans configuration. The major contributing packing forces areinteractions and weak but influential C-HÁ Á ÁO hydrogen bonds.
## Abstract A novel and efficient method of synthesis of 3-substituted derivatives of pentane-2,4-dione is proposed, wherein cheaper and easily accessible chloro derivatives are conversed into more reactive iodo derivatives. The method is based on the Finkelstein reaction for which the literature s
