The branching in 2-ethyl-1-butanol makes it harder to crystallize due to packing disruption, which results in a very low freezing point. Esters of 2-ethyl-1-butanol are similarly effected and it therefore finds application as a feedstock in the production of plasticizers and lubricants, where its presence helps reduce viscosity and lower freezing points.

Thus reaction of thiophene with butyl lithium gives 2-lithiothiophene, also called 2-thienyllithium. This reagent reacts with electrophiles to give thienyl derivatives, such as the thiol. [25] Oxidation of thienyllithium gives 2,2'-dithienyl, (C 4 H 3 S) 2. Thienyl lithium is employed in the preparation of higher order mixed cuprates. [26]
Diacetylene has been identified in the atmosphere of Titan and in the protoplanetary nebula CRL 618 by its characteristic vibrational spectrum.It is proposed to arise by a reaction between acetylene and the ethynyl radical (C 2 H), which is produced when acetylene undergoes photolysis.
The Lewis acid SnCl 2, a reducing agent in THF/EtOH solvent, replaces NO 2 with NH 2, which is subsequently replaced by iodine upon the addition of NaNO 2, H 2 SO 4, and KI to yield 3,5-dibromoiodobenzene. In this step, the Sandmeyer reaction converts the primary amino group (NH 2) to a diazonium leaving group (N 2), which is subsequently ...
