How to synthesize 2,2-diiodo-4-methyl-heptane from ethyne and 2-methylpentane? H- Ca C-H
choose a starting material (4-methyl-2-pentanone,
2-methyl-3-pentanone, 2,3-dimethylbutanal) and a reagent from A-F
to synthesize 2,2-dimethoxy-4-methylpentane.
Choose a starting material and a reagent (A-F) to synthesize the given product. When [Select ] is treated with (Select ] it will produce 2,2-dimethoxy-4- methylpentane. REAGENTS C. A. Jones' reagent, Croz in CH3MgBr (in CH3OH ether) (excess) followed by acid-catalyst, H30(+) workup heat (-H20) H₂O(+) NaBH4 in CH3OH (CH2)5NH (piperidine) N2H4 KOH & acid-catalyst, strong heat heat (-H20)
Covert ethylene to acetic acid? 17. Show how you synthesize 4-methyl-hex-2-yne? 18. Convert 2,2-dichloropentane to pent-2-yne?
Show how you could synthesize prop-1-yne from: 1. 2-bromopropane 2. Propan-1-ol 3. 1,2-dichloropropane 4. Ethyne Thank you!!!
purpose a sythetic route using only 2-methyl propene and
ethyne
