What key element is used in the Heck reaction?
Palladium
Platinum
Gold
Silver
Answer
Palladium plays a pivotal role in the Heck reaction, a versatile carbon-carbon bond-forming reaction in organic chemistry. It serves as a catalyst, facilitating the coupling of aryl or vinyl halides with alkenes or alkynes under mild reaction conditions. The reaction proceeds via a catalytic cycle involving palladium intermediates, enabling the formation of various carbon-carbon bonds with high regio- and stereoselectivity.
