Vedclass · Answer

(C) The conversion involves transforming a ketone into an alkane with a longer carbon chain. $1$. The Wittig reaction between the ketone and the ylide $(C_6H_5)_3P^{+}-C^{-}HCH_2CH_3$ produces an alkene. $2$. Hydroboration-oxidation (using $B_2H_6$ followed by $CH_3CO_2H$ or $H_2O_2/OH^-$) typically adds an $-OH$ group,but here the sequence is used to reduce the alkene to the alkane. Option $C$ correctly uses the Wittig reaction followed by hydroboration-deboronation to achieve the final product.

Which of the following sets of reagents,used in the order shown,would successfully accomplish the conversion shown?
