A HIGH YIELDING, REPRODUCIBLE SYNTHESIS OF TRIMETHYLSILYLKETENE
ABSTRACT A two-step sequence for the preparation of trimethylsilylketene, from chloroacetaldehyde diethyl acetal via ethoxyacetylene, has been modified and optimized.
FUNCTIONALIZED IRON KETENE COMPLEXES FROM CARBONYL COUPLING REACTIONS
The solution mixture of the dinitrogen complexes Fe(CO)2(PEt3)2(N2) (1a) and [Fe(CO)2(PEt3)2]2(μ-N2) (1b) reacts with methyl or ethyl haloacetates to yield the oxidative addition products Fe(CO)2(P...
Sterically guided rearrangement of 3,3-disubstited β-lactones. A rapid construction of cycloheptano trans-fused butyrolactones
Abstract 4-Cyclohexyl 3,3-disubstituted oxetan-2-ones rearrange under Lewis acid catalysis to afford trans-fused cycloheptano butyrolactones.
