Jan 10, 2021 · A synthesis reaction or direct combination reaction reacts two or more simple elements or compounds to form a more complex product. A synthesis reaction is one of the four main types of chemical reactions, along with decomposition, single replacement, and double replacement reactions.
Jul 12, 2023 · For a given target molecule, several different reaction sequences may serve to accomplish its synthesis. Indeed, new synthetic routes to known compounds continue to be reported, particularly as new reactions are developed and applied to difficult transformations.

For example, treatment of 1-bromooctane with a twofold excess of ammonia leads to a mixture containing only 45% octylamine. A nearly equal amount of dioctylamine is produced by double alkylation, along with smaller amounts of trioctylamine and tetraoctylammonium bromide.
Feb 13, 2019 · The following three examples illustrate strategies for developing multi-step syntheses from the reactions studied in the first ten chapters of this text. It is helpful to systematically look for structural changes beginning with the carbon chain and brainstorm relevant functional group conversion reactions.
