Synthesis of gem-difluoroalkenes via β-fluoride elimination of organorhodium(I)

Treatment of α-(trifluoromethyl)styrenes with arylboronic esters and MeMgCl in the presence of a rhodium(I) catalyst affords gem-difluoroalkenes. The reaction proceeds through the addition of arylrhodium(I) species across the electron-deficient carbon-carbon double bond and the subsequent β-fluoride elimination. Copyright

1,1,2-triphenylpropane and -propene derivatives

A novel 1,1,2-triphenylpropene derivative, namely: STR1 acts on the endocrine system of rats. It exerts oestrogenic or antioestrogenic effects of varying strength in rats, and furthermore inhibits the growth of the mammary tumor induced by 7,12-dimethyl-benz(a)anthracene in rats.

DETERMINATION OF THE CONFIGURATION OF DIASTEREOMERIC ETHANE DERIVATIVES BY 1 H NMR AND 13 C NMR SPECTROSCOPY
