A new oxidative coupling protocol for amide bond formation has been developed (see scheme). The method provides an efficient and practical route for the synthesis of tertiary amides from readily available tertiary amines and aldehydes in the presence of a simple FeCl2 catalyst. Mechanistic studies indicated that a peroxide and an iminium ion act as the reactive intermediates in this oxidative amidation

A new reactivity pattern of α‐aminoalkyl radicals, involving nucleophilicattack on CN triplebonds under thermal conditions, has been developed to construct α‐amino nitriles. In contrast to previous CH functionalization of tertiary amines involving α‐aminoalkyl radicals, this methodology does not require the use of photocatalytic conditions or a transition‐metal catalyst. Inexpensive and nontoxic

catalysts for directC‐3 alkylation of indoles, giving the desired products in high yields (up to 82 % based on 60–95 % substrate conversions). These ruthenium compounds catalyze oxidative couplingreactions of a wide variety of anilines and indoles bearing electron‐withdrawing or electron‐donating substituents with high regioselectivity when using tBuOOH as an oxidant, resulting in the alkylation of N‐arylindoles
