Reaction product Beilstein database

By using C NMR spectroscopy and single crystal X-ray analysis, the previous claims for the isolation of thiaziridines <1896CB59> (see Beilstein database) were shown to be erroneous <2005JSF111>. However, although the intermediacy of thiaziridines cannot be excluded in these and similar sulfur-transfer reactions, the addition of sulfur to aldimines results in the formation of isolable thioamides as products, not thiaziridines <2005JSF111>. 

Other useful databases available from STN include Beilstein and CASREACTS. As described in Section 29.10, Beilstein is very useful to organic chemists. Currently, there are more than 3.5 million compounds listed in the database. You can use the CAS Numbers to help in a search that has the potential of going back to 1830. CASREACTS is a chemical reactions database derived from over 100 journals covered by Chemical Abstracts, starting in 1985. With this database, you can specify a starting material and a product using the CAS Numbers. Further information on CA Online, Beilstein, CASREACTS, and other databases can be obtained from the following references ...
