Title:
CYCLOPROPENIUM SALT AND ITS PREPARATION
Document Type and Number:
Japanese Patent JPS5639027
Kind Code:
A
Abstract:
NEW MATERIAL:A cyclopropenium salt of formula I (R, R' and R" are cyclopropyl which may be substituted with hydrocarbon group or halogen; X- is anion).
EXAMPLE: Cyclopropenium tetrafluoroborate.
USE: A phase-transfer catalyst, a fluorine ion catalyst, a low-melting molten salt solvent, a nonaqueous solvent, and a surface active agent. It has a relatively simple structure, and nevertheless, it has remarkably high stability as can be seen in the stability constant of as high as 10.0.
PROCESS: The compound of formula I is prepared by the addition reaction of a cyclopropyl halogenocarbene of formula II (Y is halogen) with a cyclopropylacetylene of formula R"-C≡C-R".
