[Display omitted] • A novel nickel-catalyzed carbonylation of arylboronic acids. • A new carbonylative procedure toward benzyl benzoates. • Facile synthesis of 18O-labeled esters. Here, we report a nickel-catalyzed carbonylation of arylboronic acids and alkylarenes to benzyl benzoates. The reaction was well tolerated by various functional groups, resulting in the formation of wide range of functional group substituted esters in moderate to good yields. Furthermore, the reaction also allowed for the synthesis of 18O-labeled esters. [ABSTRACT FROM AUTHOR]

Alkynones represent one class of interesting building block which are frequently founded in a variety of biologically active compounds.[1] They have been emerged as key intermediates in the synthesis of various natural products and heterocycles.[2] Therefore, a considerable interest has been attracted and numerous strategies have been explored for the synthesis of alkynones. The traditional methods mainly rely on the reactions of acid chlorides with terminal alkynes.>[3–4] However, some drawbacks remain existing, including high reaction temperature, unstable acid chlorides, and poor functional group tolerance.

• A palladium-catalyzed reductive carbonylation reaction has been developed for the synthesis of quinazolines. • Quinazolines were obtained in moderate to good yields from N-(2-iodophenyl)benzimidamide. • Silane act as better nucleophile than amine. A palladium-catalyzed reductive carbonylation reaction has been developed for the synthesis of quinazolines. With N-(2-iodophenyl)benzimidamide as starting materials, a series of quinazolines were obtained through the aromatic aldehyde intermediates in moderate to good yields with good functional group compatibilities. In this system, silane act as better nucleophile than amidine. [Display omitted] [ABSTRACT FROM AUTHOR]
