The stereodifferentiation of the baker's yeast reduction of β-ketoesters is improved by exposing this reaction to 300–400 nm UV light and via a new method entitled ‘two-substrate application’. Both routes are accomplished by selectively interf

The photolysis of Fe(CO)3(η4-s-cis-1,3-butadiene) (1) and Fe(CO)4(η2-1,3-butadiene) (2), formerly studied in low-temperature matrixes, is reexamined in cyclohexane solution at ambient temperature using time-resolved IR spectroscopy in the ν(CO) re
