Canonical JSON (keys sorted, no spaces, UTF-8). Its SHA-256 is the hash on chain.
{"abstract":"The synthesis of dimethyldioxirane (DMD/DMDO) is as complicated as its storage. It should be used within a week after its synthesis. Developments were gained in the synthetic procedure of DMD/DMDO in two steps and enough yield was obtained at moderate temperature compared to literature procedures (-78 oC). The dry ice before trap was replaced with a condenser containing chilled methanol which also resulted the condensation of DMD/DMDO back from the vacuum trap. Diethyl formylphosphonate 6 was synthesized by the oxidation of diazomethylphosphonate 5 with DMD/DMDO at different temperatures starting from -78 to 0 oC.","abstract_source":"original","authors":["Said Nadeem","Ayhan Sıtkı Demir","İlke Şimşek","Muhammad Raza Shah"],"date":"2014","doi":"10.5281/zenodo.23591228","id":119,"issue":3,"journal":{"issn":"2651-4338","name":"Journal of Ongoing Chemical Research"},"pdf_sha256":"becd7c8b4516203c359cfe13ac7e8c254acbb79766e44e5ef67415f7a4aad754","schema":"scimatic-article/1","title":"DEVELOPMENTS IN THE PREPARATION OF DIMETHYLDIOXIRANE (DMD/DMDO)","volume":1}
