WebJan 31, 2024 · Sigmatropic Rearrangements. In a sigmatropic reaction a σ bond 'migrates' across a conjugated system to a new site. If ' [ n, m] sigmatropic rearrangement' has n = 1, then one end of the bond that moves remains attached to its original atom — the n refers to the fact that the other end of the bond migrates across n atoms. WebFeb 12, 2024 · 7.1: Catalytic Converters. A catalytic converter is a device used to reduce the emissions from an internal combustion engine (used in most modern day automobiles and vehicles). Not enough oxygen is available to oxidize the carbon fuel in these engines completely into carbon dioxide and water; thus toxic by-products are produced.
