Given reaction: Addition of a methyl group at the end → possible via alkynides
Possible sequence of reactions:
1. Halogenation → form vicinal dihalides (Br2)
2. Double elimination + deprotonation → form alkyne then alkynide (excess NaNH2)
In each reaction box, place the best reagent and conditions from the list below
Br2 excess NaNH2 PBr3 2 equiv. NaNH2 NaBH4 CH3CH2Br H2, Lindlar catalyst CH3Br Na, NH3 (l) HBr BH3/THF H20, H2SO4, HgSO4 H2O2, NaOH, H20
