Abstract

In the hydroformylation of 1,1,1‐trideuterio‐2‐butene with Rh~4~ (CO)~12~ the deuterated pentanals formed contain 75% of 5,5,5‐trideuterio‐pentanal, the rest being substantially 2,2‐dideuterio‐pentanal. On the contrary, using Co~2~ (CO)~8~ as the catalyst precursor, position 1 and 4 are formylated to the same extent.

The thermal unimolecular decomposition of diethyl carbonate-1,1,1,2,2-d5 has been examined in the high-pressure-limiting region. The observed chemistry is consistent with a simple, competitive two-channel model: The intramolecular isotope effect k H / k D has been determined, and the relative Arrhe

The thermal decomposition of deuterated ethyl chloride CHzDCHzCl was studied in a static system in the pressure range of 0.1-26 torr, and the Arrhenius expression for the overall decomposition at the high-pressure limit and in the temperature range of 670-1100 K was found to be k , = 1013.33\*0.10 e
