Chapter 12, Problem 29P
Interpretation Introduction
Interpretation:
The vinyl halides required to synthesize each of the given compounds by Heck coupling has to be determined.
Concept introduction:
Organometallic compound it can be defined as the compound which contain Carbon – Metal bond.- The carbon attached to the halogen in an
alkyl halide is an electrophile, whereas the carbon attached to the metal in an organometallic compound is a nucleophile. - Heck reaction: A reaction that couples an aryl halide or vinyl halide with an
alkene . - Grignard reagent:
The compound that results when magnesium is inserted between the carbon atom and the halogen of an alkyl halide like
