H+/ H2O
breaks O "Hat" and crated OH in anti formation on each side of broken "hat
OH-/ H+
breaks O "Hat" and crated OH in anti formation on each side of broken "hat
CH3Cl3/ KOH
Breaks double bond and adds "hat" C with 2 attached Cl bonds.
CHBr3/ KOH
Breaks double bond and adds C in "hat" formation with 2 attached BR
NaNH2 with terminal Triple bond
Removes H form terminal Carbon and makes that terminal Carbon have a negative charge.
CH3Br reacting with negatively charged triple bonded carbon.
adds CH3 on negatively charged carbon
CH2CH(Br)CH3 reacting with negatively charged triple bonded carbon.
adds H2 to negatively charged carbon and makes triple bond a double bond.
H3C-C(triple bond)C- then H3O+
negative Carbon attaches to positive carbon and "attaches" to form new molecule
NaNH2/ 100C/ H3O+
Removes 2 Br and creates a terminal triple bond. Remember to add appropriate H to each carbon
KOH/ 200C
Removes 2 Br and creates a non terminal Triple bond. Remember to add appropriate H to each Carbon.
Br2 (1eq) to triple bond
adds 2 Br (one to each side of triple bond) stereochemistry can not be controlled
Br2 (2eq) to triple bond
adds 2 Br to the Same carbon. Remember to add H to other side of broken tripple bond.
HBr/ RooR
Add Br to triple bond to create double bond.
H2/ Pt, Pd, or Ni
add H to all Carbons. There will be NO double or triple bonds any more.
H2, Pd(BaSO4) / quinoine
Adds H to each carbon on triple bond. Makes triple bond a double bond. (Z stereochemistry)
Na/ NH3
Adds H to each side of triple bond to make a double bond. (E stereochemistry)
HgSO4, H20 / H2SO4
Adds double bonded O to Carbon (not terminal carbon) and stabilizes other carbon by adding H2
1. Sia2BH 2.H2O2/OH-
adds double bonded O to triple bonded terminal carbon. Stabilizes other carbon by adding H2
KMNO4, H2O / neutral or cold (when triple bond is NOT terminal)
add double bonded O to each carbon involved with Triple bond.
KMNO4, H2O / neutral or cold (when triple bond IS terminal)
Add double bonded O to both carbons involved with triple bond and a OH onto terminal carbon.
