Check 20+ pages what is the leaving group in the reaction shown below analysis in Google Sheet format. Sodium amide is not a strong enough base to deprotonate the alkyne. Grignard reaction can be written as. Consider the following transformation. Read also reaction and what is the leaving group in the reaction shown below 12The two reactions below is the same reaction done with two different leaving groups.
The 3 important leaving groups to know. This is because the better leaving group leaves faster and thus the reaction can proceed faster.

In the second fast step the carbocation reacts with the nucleophile to form the product.
-OCH 1 CH3 -So iv. Good leaving groups are the conjugate bases of strong acids. Indeed they are even less effective in this role than are hydroxyl and alkoxyl groups. RX Mg RMgX RMgX R1 - CO - R2 R1R2 RC-OH a 3o or tert-alcohol where R R1 and R2 are alkyl phenyl or aryl groups and X is a suitable halogen. This is due to the formation of a resonance stabilized structure upon leaving. Expert Answer 100 4 ratings.
