Carbene Reactions, IV. Addition of Dimethoxycarbene to C—C Multiple BondsDimethoxycarbene (1) adds to diethyl fumarate or maleate to form diethyl 3,3-dimethoxycyclopropane-trans-1,2-dicarboxylate (6). Addition to styrene derivatives yields similarly 3,3-dimethoxycyclopropanes, whereas addition to acetylenedicarboxylate, phenylacetylene or diphenylketene led to 1:2-adducts of varying structure.
Notes:
Dimethoxycarben (1) addiert an Fumar- oder Maleinester unter Bildung von 3,3-Dimethoxy-cyclopropan-trans-1,2-dicarbonester (6). Bei der Addition an Styrol-Derivate entstehen ebenfalls 3,3-Dimethoxycyclopropane, während mit Acetylendicarbonester, Phenylacetylen oder Diphenylketen 1:2-Addukte unterschiedlicher Struktur resultieren.
