A Convenient and Efficient Workup of Ozonolysis Reactions Using Triethylamine
摘要:
Comparison were made between triethylamine and methyl sulfide for their use as a quenching agent in the ozonolysis of a variety of alkenes. The reactions involving triethylamine often gave better yields and proceeded faster than those of involving methyl sulfide. The role of triethylamine played as base instead of reducing agent in the reaction.
E1cb mechanism is the overwhelming process in the reaction of bases and ozonides. As a quenching agent in the ozonolysis of a variety of alkenes, the reactions involving triethylamine often gave better yields and proceeded faster than those involving methyl sulfide. On the other hand, in the presence of 4 Å molecular sieves, the secondary amines reacted with mono- and 1,1-di-substituted ozonides to afford

Treatment of indene ozonide with chlorosulfonic acid in methylene chloride at 0 °C affords a crystalline tetramer of the ozonide, the structure of which is shown by X-ray crystallographic analysis to contain a novel 20-membered dodecaoxacycloicosane ring system.
