eng	Synthesis of boron heterocycles from β-enaminoamides and diazonium salt	β-Enaminoamides 1 having phenyl at amide nitrogen react with 4-methylbenzenediazonium tetraphenylborate to give six membered heterocyclic system with four-coordinate boron atom (an arrangement of the heteroatoms in the cycles –N–B(Ph)2–N–, –N–B(Ph)2–O– or –N–B(Ph)2–N–N–) (see Scheme 1). Proportions of the products change depending on the reaction conditions and on the structure of starting enaminoamide.[1] β-Enaminoamides 5 having –CONH2 or –CONHMe react with the same diazonium tetraphenylborate to give new boron heterocycle - triazaborinone 6 (Scheme 2).[2] Oxazaborines and diazaborines, major products from the reaction of enaminoamides 1, were also isolated as minor products.
