Chemical research careers are more diverse than they might first appear, as there are many different reasons to conduct research and many possible environments. 122-75-8, Name is N1,N2-Dibenzylethane-1,2-diamine diacetate, SMILES is CC(O)=O.CC(O)=O.C1(CNCCNCC2=CC=CC=C2)=CC=CC=C1, in an article , author is Ross, John F., once mentioned of 122-75-8, Electric Literature of 122-75-8.
The cycloaddition reactions of nitrile sulfides have been used to prepare benzisothiazole quinones and 1,2-benzisothiazole-5,6-dicarboxylates. The nitrile sulfides, generated by thermal decarboxylation of 1,3,4-oxathiazol-2-ones, reacted with 1,4-naphthoquinone to afford 3-substituted naphtho[2,3-d]isothiazole-4,9-diones (17), together with nitriles as by-products. The corresponding reactions with 1,4-benzoquinone yielded regioisomeric mixtures of 2: 1 adducts. The 1,2-benzisothiazole-5,6-dicarboxylates were synthesised by a sequence involving both nitrile sulfide and Diels-Alder cycloaddition reactions. Dimethyl 3-phenylisothiazole-4,5-dicarboxylate (34), prepared from benzonitrile sulfide and dimethyl acetylenedicarboxylate (DMAD), was converted into the 4,5-bis(dibromomethyl) analogue 37 via the bis(dihydroxymethyl) compound 35. Treatment of 37 with sodium iodide in the presence of DMAD afforded dimethyl 3-phenyl-1,2-benzisothiazole-5,6-dicarboxylate (30) via the isothiazole o-quinodimethane 32.
