Title: Alkylation of 4,5‐dichloropyridazin‐6‐one with α,ω‐dibromoalkanes or 4,5‐dichloro‐1‐(ω‐bromoalkyl)pyridazin‐6‐ones
Abstract:Abstract Alkylations of 4,5‐dichloropyridazin‐6‐one (1) with dibromoalkanes 2 or 3 in the presence of potassium carbonate or tetrabutylammonium bromide/potassium hydroxide were investigated under rest...Abstract Alkylations of 4,5‐dichloropyridazin‐6‐one (1) with dibromoalkanes 2 or 3 in the presence of potassium carbonate or tetrabutylammonium bromide/potassium hydroxide were investigated under restricted condition. Reactions of 1 with 2 or 3, except for 2b and 3b , in the presence of potassium carbonate or tetrabutylammonium bromide/potassium hydroxide gave only the N ‐alkylation products 3 and/or 4. Alkylation of 1 with 2b or 3b in the presence of potassium carbonate yielded the N ‐alkylation products 3b and/or 4b and the O ‐alkylation product 5 as the main product, whereas treatment of 1 with 2b or 3b in the presence of tetrabutylammonium bromide/potassium hydroxide afforded selectively the N ‐alkylation products 3b and/or 4b.Read More
