Tlgllc acid Is esterlfied with the amino-alcohol teloldlne in the alkaloid meteloidlne, which occurs with hyoscyamlne and hyoscine in the plant Datura meteloides. Several other tiglic acid esters have been found In higher plants(l). Robinson s al. (2) discovered that tigllc acid was formed from ISOl
The kinetics of 2-bromo-3-methylbutyric acid in the gas phase was studied over the temperature range of 309.3-357.0"C and pressure range of 15.5-100.0 torr. This process, in seasoned static reaction vessels and in the presence of the free radical inhibitor cyclohexene, is homogeneous, unimolecular,
The elimination kinetics of the title compounds have been examined over the temperature range of 270-320Β°C and pressure range of 19-117 torr. The reactions, carried out in seasoned vessels, with the free-radical suppressor toluene always present, are homogeneous, unimolecular, and follow a first-ord
