1.Understanding Aryl and Alkyl Halides: - Aryl halides are compounds where a halogen atom is bonded to an aromatic ring (like benzene), while alkyl halides have halogen atoms attached to aliphatic carbon chains. 2.Bonding Characteristics:

Relative activity of halogenated arenes, alkanes, and alkanes in the Suzuki reaction catalyzed with acyclic diaminocarbene complex of palladium has been investigated. Under all the investigated conditions, 4-iodoanisole has been more active than the alkyl halides. The reaction with 4-methyl-1-(chlorom...

This operationally straightforward, metal-free and modular transformation forms tertiary amines, without structural constraint, via the coupling of aldehydes and secondary amines with alkyl halides. The structural and functional diversity of these readily available precursors provides a versatile and flexible ...

The direct reductive cross-coupling of alkyl halides with aryl halides is described. The transformation is efficient (equimolar amounts of the starting materials are used), generally high-yielding (all but one between 55 and 88% yield), highly functional-group-tolerant [OH, NHBoc, NHCbz, Bpin...
However, the reaction completely shut down by using Et3N, a frequently used base in palladium-catalyzed Sonogashira coupling of aryl halides (entry 10)11. Lowering the amount of catalyst or reaction temperature led to a reduced yield to different extent (entries 11–12). Control experiments ...
