Iyoda, Masahiko published the artcileSynthesis and properties of a bisdehydro[14]annuleno[c]furan and an ortho-annelated tetrakisdehydro[14]annuleno[14]annulene, Recommanded Product: Diethyltrichloromethylphosphonate, the publication is Bulletin of the Chemical Society of Japan (1994), 67(3), 778-91, database is CAplus.
A bisdehydro[14]annuleno[c]furan I and a tetrakisdehydro[14]annuleno[14]annulene II have been synthesized; their properties and effects of annulation on annulene rings are discussed on the basis of 1H NMR and electronic spectra. Attempts to synthesize the related [14]annuleno[16]annuleno[14]annulene are also described.
Bulletin of the Chemical Society of Japan published new progress about 866-23-9. 866-23-9 belongs to chlorides-buliding-blocks, auxiliary class Aliphatic Chain, name is Diethyltrichloromethylphosphonate, and the molecular formula is C5H10Cl3O3P, Recommanded Product: Diethyltrichloromethylphosphonate.
