Glycidic esters can easily be converted to aldehydes (2-40). The reaction has been extended to the formation of analogous aziridines by treatment of an imine with an a-halo ester or an a-halo N,N-disubstituted amide and f-BuOK in the solvent 1,2-dimethoxy-ethane.636 However, yields were not high. Acid-catalyzed Darzens reactions have also been reported.637 See also 6-61.

Figure 12. F cycle constant current charge curves of synthetic graphite LONZA KS 44 (i) using 1 MLiN(S02CF3)2 in EC.DME (dimethoxy ethane, CH3OCH2CH2OCH3) (3 2) as electrolyte. The measurement was stopped when the graphite was exfoliated, (ii) using 1 M LiN(S02CF3)2 in EC F-DME (partially fluorinated dimethoxy ethane, CH3OCF2CF2OCH3) (3 2) as electrolyte, i = 20 mA g1, cut-off = 0.0 V vs. Li/Li+ (adaptedfrom [12]).

PC = propylene carbonate DN = 1,3-dioxolane EC = ethylene carbonate 3-MeS-3 = methyl sulfolane DME = dimethoxy ethane THF = tetrahydrofuran S = sulfolane DMSO = dimethyl sulfoxide, DEE = diethyl ether, 2-Me-F = 2 methyl furan 2-MeDN = 2-methyl 1,3-dioxolane MA = methylacetate DMM = dimethoxymethane 2-MeOTHF = 2 methoxytetrahydrofuran BL = y-butyrolactone NM = nitromethane AN = acetonitrile MF = methyl formate DEC = diethyl carbonate DMC = dimethyl carbonate. 

Figure 9-5. Structures of complexes of a AgBF4 2-dimethoxy ethane complex, b AgBF4 , 2-dimethoxy ethane-ethylene adduct where 1,2-dimethoxy ethane is a model compound of poly(ethylene oxide) [15]. The silver ion is coordinated by two oxygen atoms from 1,2-dimethoxy ethane and two F atoms from the anion to make silver-polymer complexes, when AgBF4 is complexed with 1,2-dimethoxy ethane. One of the two F atoms bound to the silver ion is replaced by an ethylene molecule, when one ethylene molecule approaches the complex in an ethylene environment.
