manganese catalyzed coupling of alcohols with phosphorus ylides. The selectivity in the coupling of primary alcohols with phosphorus ylides to form carbon‐carbon single (C−C) and carbon‐carbon double (C=C) bonds can be controlled by the ligands. In the conversion of more challenging secondary alcohols with phosphorus ylides the selectivity towards the formation of C−C vs. C=C bonds can be controlled by the

A copper-catalyzed alkoxycarbonylation transformation of unactivated alkyl iodides has been developed. Various alkyl iodides can be converted into the corresponding tert-butyl esters in good yields. NaOtBu acts as both a nucleophile and a base. Moreover, other types of aliphatic esters can also be obtained in moderated yields if extra alcohols are added. Both primary and secondary alkyl alcohols can
