Vedclass · Answer

(A) The transformation involves the anti-Markovnikov hydration of an alkene followed by the oxidation of the resulting primary alcohol to an aldehyde.$1$. Hydroboration-oxidation: The reaction of $Cyclohexyl-CH_2-CH=CH_2$ with $(i) BH_3$ followed by $(ii) H_2O_2 / \stackrel{\ominus}{O}H$ yields the primary alcohol,$Cyclohexyl-CH_2-CH_2-CH_2OH$.$2$. Oxidation: The primary alcohol is then oxidized to an aldehyde using a mild oxidizing agent like $PCC$ (Pyridinium chlorochromate),which stops the oxidation at the aldehyde stage.Therefore,the correct sequence of reagents is $(i) BH_3, (ii) H_2O_2 / \stackrel{\ominus}{O}H, (iii) PCC$.

Identify the correct reagents that would bring about the following transformation: $Cyclohexyl-CH_2-CH=CH_2 \rightarrow Cyclohexyl-CH_2-CH_2-CH_2-CHO$
