1
Q
reagents and conditions for acylation
A
CH3COCl reagent
AlCl3 conditions
2
Q
reagent for nucleophilic addition of aldehydes
A
NaBH4
3
Q
NMR solvents and reference
A
CCl4 and CDCl3 solvents
TMS reference
4
Q
why are these used as references
A
Neither contain H
CCl4 is non polar (good for non polar molecules)
CDCl3 is polar (good for polar molecules)
5
Q
why is TMS used
A
lots of equivalent H to use as a reference
creates 1 peak away from others
volatile/easy to remove
