Efforts to generate organomanganese reagents under ball-milling conditions have led to the serendipitous discovery that manganese metal can mediate the reductive dimerization of arylidene malonates. The newly uncovered process has been optimized and its mechanism explored using CV measurements, radical trapping experiments, EPR spectroscopy, and solution control reactions. This unique reactivity can also be translated to solution whereupon pre-milling of the manganese is required.
Preparation method of malonic ester
-
Paragraph 0059-0068, (2018/04/01)
The invention provides a preparation method of malonic ester. Malonic ester is obtained by using 70-80 wt% of cyanoacetic acid, hydrogen chloride-alcoholic solution and corresponding alcohol as raw materials, and is subjected to the process of esterification, dealcoholic water, alcoholysis esterification, dealcoholization, neutralization and distillation. The preparation method chooses the cyanoacetic acid of reasonable concentration, reduces the heat-sensitive reaction of distillation dehydration when obtaining high concentration cyanoacetic acid, and reduces the difficulty of dehydration ofthe cyanoacetic acid raw materials; the method is high in operability, reasonable and economy, reduces the discharge of three wastes greatly, and has good social benefit.
Transformation of amides into esters by the use of chlorotrimethylsilane
Xue, Cuihua,Luo, Fen-Tair
, p. 359 - 362 (2015/02/02)
A mild transformation of various amides and imides into the corresponding esters and diesters in good yields by using chlorotrimethylsilane and alcohols at rt are described. Either primary, secondary, or tertiary amide or imide can be used in this transformation. Primary and secondary alcohols gave better yields than tertiary alcohols.
