Lol yes let me give it one more try. once u from Butane u can UV brominate to get 2-bromo butane than elminate using a strong base to get 2-butene. Than use NBS and DMSO to get allyic bromination yieldint 1-bromo-2-butene. Than use H2 and catalyst. to get 1 bromo butane. Than elminate to get 1-butene. Use dmso and nbs to get 3-bromo-1-butene. Than finish it off with a gilman reagent and adda methyl. lol

nvm for the first one i think i got it . Use socl2 and pyridine to get chloroethane than gilamn reagent to get butane than uv brominate than strong base to elminate and then NBS/dmso to allyic brominate and then gilman one more time ? Edit: uv bromination wont work cuz zaitsev product will form nvm.

Hello, I need help synthesizing 3-methyl-but-1-ene and 2,3dimethylbutane using only ethanol as my organic starting material. Methyl-iodide can be used an also any other inorganic reagent or organic solvent. Keep in mind please that I am only in orgo2 and have not gotten past diels alder reactions. I want to see if my proposed solution makes sense. My proposed for 3-methyl-but-1-ene I was thinking of using SOCL2 in pyridine to get chloroethyl and then use a gilman reagent to add on ch2ch3 resulting in a butane. Than use br2 with UV to get a 2-bromobutane and then use gilman reagent to get 2 methylbutane. From here I am stuck. Maybe i did something wrong? For the 2nd one. I am completely lost maybe telling me where to start off will help. Thank you very much!
