CATHODIC SYNTHESIS OF ESTERS OF 1,1,2,2-CYCLOALKANETETRACARBOXYLIC ACIDS DERIVED FROM 1,1,2,2-ETHANE- OR ETHYLENECARBOXYLATE ESTERS
Vasil'ev, A. A.,Zvolinskii, V. I.,Petrosyan, V. A.
, p. 180 - 183 (1992)
The cathodic electrolysis of esters of 1,1,2,2-ethane- or ethylenetetracarboxylic acids in the presence of dihaloalkanes leads to esters of 1,1,2,2-cycloalkanetetracarboxylic acids. Keywords: acyclic compounds, esters, alkyl bromides, electrochemical synthesis, electrolytic reduction.
Electrochemical oxidation of malonic esters in acetonitrile in the presence of iodides as mediators
Fedukovich,Elinson,Nikishin
, p. 599 - 602 (1997)
Electrochemical oxidation of malonic esters in acetonitrile in the presence of iodides follows two different pathways depending on the nature of the cation. In the presence of LiI, alkyl 1,1,2,2,3,3-propanetetracarboxylates were obtained in 85-98% yields. In the presence of NaI, KI, or Bu4NI, the formation of 1,1,2,2-ethanetetracarboxylates and their subsequent dehydrogenation to ethenetetracarboxylates was the main reaction pathway.

Simple synthesis of tetra-acceptor-substituted alkenes by the formal dehydrodimerization of malonates
Linker, Torsten,Linker, Ursula
, p. 902 - 904 (2000)
Only two steps are required for the synthesis of tetra-acceptor- substituted alkenes from simple malonates in excellent yields [Eq. (1)]. The method is characterized by cheap and commercially available precursors, and ultrasound remarkably accelerates the radical reaction as well as the successive Knoevenagel reaction.
Cu-Mediated arylselenylation of aryl halides with trifluoromethyl aryl selenonium ylides
Wu, Shuai,Shi, Jin,Zhang, Cheng-Pan
, p. 7468 - 7473 (2019/08/20)
An unprecedented arylselenylation of aryl halides with trifluoromethyl aryl selenonium ylides in the presence of copper is described. The reaction proceeded at 100-140 °C under ligand- and additive-free conditions for 3-20 h to form a variety of unsymmetrical diaryl selenides in good to high yields. Arylselenylation is easy to operate, has good functional group tolerance, and demonstrates the different reaction profiles of trifluoromethyl aryl selenonium ylides from the homologous trifluoromethyl aryl sulfonium ylides.
