Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 4020-99-9, Name is Methoxydiphenylphosphine, Product Details of 4020-99-9.
TADDOL (=alpha,alpha,alpha?,alpha?-Tetraaryl-1,3- dioxolane-4,5-dimethanol) and the corresponding dichloride are converted to TADDAMINs (=(4S,5S)-2,2,N,N?-tetramethyl-alpha,alpha,alpha?, alpha?-tetraphenyl-1,3-dioxolan-4,5-dimethanamines) (Scheme 2) and ureas, 12-15, and to TADDOP derivatives with seven-membered O-P-O ester rings (Schemes 3 and 4). Cl/P-Replacement via the Michaelis-Arbuzov reaction (Scheme 7) on mono- and dichlorides, derived from TADDOL, are described. It was not possible to obtain phosphines with the P-atom attached to the benzhydrylic C-atom of the TADDOL skeleton (Schemes 6 and 7). The X-ray crystal structures (Figs. 1 and 2) of ten of the more than 30 new TADDOL derivatives are discussed. Full experimental details are presented. Copyright
