Synthesis of new heterocycles containing more than one 1,2,3-thia or selenadiazole rings
Al-Smadi, Mousa
, p. 915 - 918 (2007)
(Chemical Equation Presented) The diketones 2a-d with different alkyl chain length are used for the synthesis of di-1,2,3-thia or selenadiazole derivatives 4a-d and 5a-d. The diketones 2a-d where prepared by a unique method through the reaction between the corresponding dibromoalkanes 1a-d and ethyl acetoacetate, which are transformed into the corresponding semicarbazone derivatives 3a-d. The di-1,2,3-thia or selenadiazole derivatives 4a-d and 5a-d were prepared from the semicarbazones derivatives 3a-d on oxidative cyclization with thionyl chloride and selenium dioxide respectively in high yield.

Synthesis of methyl ketones from terminal olefins using PdCl 2/CrO3 system mimicking the Wacker process
Fernandes, Rodney A.,Bethi, Venkati
, p. 4760 - 4767 (2014/06/24)
An efficient synthesis of methyl ketones from terminal olefins using PdCl2/CrO3 system mimicking the Wacker process is developed. The method shows good functional groups compatibility, no aldehyde by-products and is operationally simple. CrO3 is the sole oxidant and replaces both Cu-salts and molecular oxygen, traditionally used in this process. The method holds potential for future applications in organic synthesis.
