DOCUMENT TYPE: Journal CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Section cross-reference(s): 29 Reaction of imidazolyl sodium with RP(O)(OEt)2 (R = Cl2CH, ClCH2, Et) gave 12-33g 1-ethylimidazole. The yield increased with increasing order of the electron withdrawing properties of the P alkyl group of the ester. The alkyl phosphonates, RP(O)(OEt)2, were prepd. in 68-90% yields by 2 methods. .
