Abstract
The incorporation of the 3-methylbenzofuran moiety into the ferrocene nucleus leading to a series of structurally novel hybrids 2-ferrocenoyl-3-methylbenzofuran derivatives has been achieved in good yields of 76-85% through the one-pot Rap-Stoermer reaction of 1-chloroacetylferrocene with 2′-hydroxyacetophenones in refluxing CH3CN with the presence of K2CO3as base and PEG-400 as catalyst. These newly-synthesised compounds could be good candidates for the development of compounds for use in medicinal chemistry.

Abstract
A simple, efficient and eco-friendly synthesis of a series of structurally new indolo[2,3- b]quinoxaline derivatives has been developed. The synthesis mainly relies on the condensation reaction of various isatins with o-phenylenediamine in water with the use of benzyltriethylammonium chloride as catalyst. The protocol is very simple, avoids toxic solvents and catalysts, is easy to work-up and is thus especially ‘green’.
