Reactions of 2,2-dimethyl-1,1-diphenylpropan-1-ol with acidic reagents: a reinvestigation of the dehydration products and isolation of a sulfonation product: Reactions of 2,2-dimethyl-1,1-diphenylpropan-1-ol with acidic reagents: a reinvestigation of the dehydration products and isolation of a sulfonation product. Scott, Heather; Shilton, Roy (Dep. Chem., Univ. Aberdeen, Aberdeen, Scot.). J. Chem. Soc., Perkin Trans. 1, (3), 247-50 (English) 1977. CODEN: JCPRB4.In this article, certain chemicals are used. Some of their cas registry numbers are 1657-60-9 and 32134-58-0 DOCUMENT TYPE: Journal CA Section: 25 (Noncondensed Aromatic Compounds) Section cross-reference(s): 27 Dehydration of Me3CCPh2(OH) (I) with 4-MeC6H4SO3H, KHSO4, oxalic acid, Ac2O-AcCl, or H2SO4 gave CH2:CMeCPh2Me (II) which rearranged rapidly to Me2CPhCPh:CH2. Previous claims (Bateman, D. E.; Marvell, C. S., 1927, Skerret, E. J.; Woodcock, D., 1952) to have prepd. II are erroneous. Prolonged treatment of I with concd. H2SO4 gave the sultone III. .
