iron carbonyl complexes have been applied in alkylation of indoles with various benzylic alcohols, aliphatic alcohols (butanol, ethanol, methanol and 2‐methylpentanol) via the hydrogen autotransfer strategy in mild reaction conditions. Experimental works highlight the role of the bifunctional iron complexes and the base. These iron complexes demonstrated a broad applicability in mildconditions and
Reaction of aliphatic olefins with synthesis gas and hydrazines in the presence of rhodium phosphine catalysts leads directly to the corresponding hydrazones. Applying Iphos as ligand good to excellent yields and high chemo- and regioselectivities were obtained in toluene under mild conditions. In case of aromatic hydrazines in situ Fischer indole synthesis can be combined with the new hydrazone preparation
