Ketene O,O-acetals which can be converted in a simple manner to fungicidal ketene O,N-acetals are prepared by an addition reaction of a phenol with a phenoxyalkyne. A Ruland,W Reuther - US 被引量: 22发表: 1985年 The Alkoxy Substitution Reaction on α-Oxo Ketene Dithioacetals: A New...
10 Finally, we were pleased that the commonly used bioconjugation probe (DBCO-NH2) reacted with 1a to yield product 2aa with the strained alkyne moiety intact. The 2-amino N-(1-ethyoxyvinyl)pyridinium salt products are potentially valuable for medicinal chemistry as they are comprised of ...

thioalkynethioketeneNucleophilic addition to thioalkynes was investigated under various catalytic conditions with gold(I) complexes being identified as the optimal catalysts. Structural evaluation of the product revealed an unexpected cis-addition, arising from a gold-associated thioketene intermediate. Based...
ChemInform Abstract: Transition Metal‐Ketene Compounds. Part 27. Variable Electron‐Donor Ability of Alkyne Ligandsorgano‐tungsten compoundsThe reaction of the ketenyl compound (I) with the electron-rich ynamine (II) does not undergo a cyclo-addition reaction but leads via replacement and ...
