what is a phosphate donor?
A
electrophile w/ leaving group
4
Q
what is a phosphate acceptor?
A
nucleophile
5
Q
what do mg(ii) ions do to phosphorus’s electrophilicity?
A
electrophilicity enhanced by lewis acidic effect of mg(ii)
6
Q
describe the concerted model
A
like an sn2 reaction.
7
Q
addition-elimination
A
nucleophile attacks first, then leaving group is eliminated
8
Q
elimination addition
A
like an sn1 reaction (leaving group leaves, electrophile attacked)
