Organic Synthesis under High Pressure; II

All articles of this category Part 1 of this article ( Synthesis 1985 , 1-26) was concerned with practical aspects of organic synthesis under high pressure and various types of ionic reactions under such conditions. The present Part II is now concerned with some synthetic applications of high pressure technology to formally pericyclic reactions such as cycloaddition, ene, and other pericyclic reactiones. 4.
