grignard reagents Flashcards
1
Q
general formula
A
RMgX
2
Q
how to prepare a girgnard reagent
A
- haloalkane + MG IN dry ether
3
Q
grignard + CO2
A
RMgX + CO2 = RCOOMgX
HYDROLYSE IN DILUTE ACID
RCOOMgX + H2O = RCOOH + Mg(OH)X
4
Q
girgnard + CO2 product
A
- carboxylic acid
- increases length of carbon chain by one
5
Q
grignard + carbonyl
A
RMgX + R’COR’’ = RCOR’R’‘OMgX
dilute acid hydrolysis
RCOR’R’‘OMgBr + H2O = RR’R’‘OH + MgOHBr
6
Q
they are …
A
- reducing agents
- nucleophiles
