Novel preparative methods for fluoroalkyl arylsulfinyl compounds are disclosed. Fluorinated compounds as useful fluorinated compounds, intermediates, or builing blocks are disclosed. Useful applications of the fluoroalkyl arylsulfinyl compounds are shown.
The novel sulfonamides of formula I, ##STR1## in which the symbols R.sup.1 -R.sup.9, R.sup.a, R.sup.b, X, Y and n have the significance given in the description and salts thereof can be used for the treatment of circulatory disorders, especially hypertension, ischemia, vasopasms and angina pectoris.
The solvolysis reaction between benzyl chlorides and ethylene chlorohydrin has been employed for the synthesis of a series of benzyl 2-chloroethyl ethers (III) required in insecticide screening tes...
α-oxo-acetals (3b, 5b, 17, 18) through an enolization/ionization mechanism. With trifluoroethanol/sodium trifluoroethoxide, the corresponding trifluoroethyl acetals (3a and 5a) are formed. Basic hydrolysis affords 2-endo-hydroxynorbornene-2-exo-carboxylic acid (20x) and the 7-oxa analogues (22x, 23x), presumably through benzilicacidrearrangement of the α-diketones.
