WebIntroduction Bicyclo[1.1.0]butanes (BCBs 1, Fig. 1a) are a class of hydrocarbons consisting of two cyclopropane rings fused through a common C–C bond.The fused bicyclic structure is highly strained (ring strain energy ∼66 kcal mol −1, more than twice that of cyclopropane), 1 which renders BCBs valuable intermediates in ‘strain release’ chemistry for the synthesis … WebBridgeHead helpt private partijen al meer dan tien jaar om hun weg te vinden in de ingewikkelde wereld van de Rijksoverheid.
