Both SN1 and SN2 have
intermediates
Only
SN1
doesn't have a
transition-state
E1 cannot happen with
1°
Leaving group=
electronegative
Bulky base=
E1
NaOH=
E2
When the thing replacing your LG has the same
priority (same row)
, need to switch
dash to wedge
Markovnikov= add H to the side with the
most
amount of H's
E2 is a
base
dependent reaction
Bulky
base=least stable alkene
Non-bulky
base=most stable alkene
SN1=
charge
so
racemic
E1=
protic
E2=
protic
SN1=
protic
SN2=
aprotic
BH3 & THF=
Anti-Markovnikov
O3=
cutting through bond
OsO4= 2
OH's
DMS=
H
turns into
OH
How to turn OH into LG: OH +
Ts-Cl
=
OTs
X2=
epoxide
unstable=most likely
leave
Transition Metals=
Ni, Pd, Pt, Rh, Ir
How many wedges and dashes?
2 wedges
(
Os, Mn
)O4 + H2O =
2 OH's
How many wedges and dashes?
2 wedges
When deciding which side gets X when the epoxide breaks off, it's
3°>2°>1°
