2-Lithioimidazoles react normally, e.g. with acetaldehyde (Scheme 61) 〈70AHC(12)103〉; 5-lithioisothiazoles (see Scheme 62) 〈72AHC(14)1〉 and 2-lithiothiazoles Tellurium is a metalloid; it has a characteristic metallic luster, but can be pulverized to form a gray powder. The name of the element is derived from the Latin word for the Earth, tellus. It is found in the Earth's crust at a concentration of 5 ppb, making it the 72nd most abundant element.
