Devise a synthesis of 5-methyl-1-hexyne using one of the starting materials and any of the reagents below using the fewest steps possible. If you need fewer than the 3 steps allowed, enter "none" for reagents in the remaining unused steps.
Starting Materials:
(1.) HC(triple bonded)CH
(2.) HC(triple bonded)C-CH3
(3.) HC(triple bonded)C-CH2CH3
(4.) HC(triple bonded)C-CH2CH2CH2CH3
(5.) HC(triple bonded)C-CH(CH3)(CH3)
(6.) HC(triple bonded)C-C(CH3)(CH3)(CH3)
Reagents:
a. NaNH2/NH3 (l)
b. NaOH/H2O
c. iodomethane
d. idoethane
e. 1-bromopropane
f. 2-bromopropane
g. 1-bromo-3-methylbutane
h. t-butyl bromide
i. H2/ Pd on Carbon
Answer the following:
Starting Material:
Reagent for step 1:
Reagent for step 2:
Reagent for step 3:
