Cyclobutadiene is an organic compound with the formula C4H4. It is very reactive owing to its tendency to dimerize. Although the parent compound has not been isolated, some substituted derivatives are robust and a single molecule of cyclobutadiene is quite stable. Since the compound degrades by a … See more The compound is the prototypical antiaromatic hydrocarbon with 4 π-electrons. It is the smallest [n]-annulene ([4]-annulene). Its rectangular structure is the result of the Jahn–Teller effect, which distorts the … See more Several cyclobutadiene derivatives have been isolated with steric bulky substituents. Orange tetrakis (tert-butyl)cyclobutadiene arises by See more • Butadiene • Cyclobutene See more Samples of cyclobutadiene are unstable since the compound dimerizes at temperatures above 35 K by a Diels-Alder reaction. By suppressing bimolecular decomposition … See more WebSep 2, 2010 · Abstract Based on 13C NMR chemical shifts at variable temperatures it is suggested that cyclobutadienyl dications form essential intermediates in the rapid … WebEstimate the delocalization energy, in units of beta, of the cyclobutadienyl dication C4H4 from HMO theory.
