Partly cloudy with a high of 101 °F (38.3 °C). Winds variable at 6 to 9 mph (9.7 to 14.5 kph). Night - Partly cloudy. Winds W at 6 to 10 mph (9.7 to 16.1 kph). The overnight low will be 76 °F (24.4 °C ...

The defluorosilylation, mediated by silylboronates and KOtBu, proceeded smoothly at room temperature to afford various aryl silanes in good yields. Although a comparative experiment indicated that Ni ...

Designed transition metal complexes predominantly catalyze Michael addition reactions. Inorganic and organic base-catalyzed Michael addition reactions have been reported. However, known base-catalyzed ...

Cobalt has become increasingly attractive in homogeneous catalysis because of its unique characteristics and outstanding catalytic performance in addition to being cheap and earth-abundant. Hydride ...

Researchers in the Grubbs and Stoltz groups at the California Institute of Technology fortuitously discovered an attractive alternative method based on the inexpensive base potassium tert-butoxide ...

Many recent studies have used KOtBu in organic reactions that involve single electron transfer; in the literature, the electron transfer is proposed to occur either directly from the metal alkoxide or ...
