Assessment of butene-1,4-diols as starting materials for the preparation of π-Allyltricarbonyliron complexes

Abstract

This work assesses the use of butene-1,4-diols as starting materials for the synthesis of π-allyltricarbonyliron lactone complexes. It has been shown that substituents, and the use of Lewis acids, mainly ZnBr 2, in reactions with Fe 2(co) 9 in benzene under ultrasonic conditions or in THF, greatly influence the yield and the product distribution.
