An expeditious, simple, highly efficient, practical and green protocol for the N-formylation of alkyl/aryl amines and indole derivatives catalyzed by novel nano rod-shaped basic Al2O3 under solvent-free conditions has been developed. The catalyst is efficiently recycled up to the 5th run, an important point in the domain of green chemistry. The methodology provides cleaner conversion, shorter reaction times and high selectivity which makes the protocol attractive. The Royal Society of Chemistry 2012.

The N-formylation of a variety of primary and secondary amines by using aqueous formaldehyde at room temperature in open air affords the corresponding formamides in excellent yield under the catalytic influence of a gold-carbon nanotube nanohybrid. The reaction is also marked by excellent chemoselectivity, low catalyst loading, and recyclability of the catalyst.

Nano-MgO a basic catalyst was prepared by solution combustion technique. It was characterized by powder XRD, SEM, BET and TEM analyses. It was used as a catalyst for the study of microwave-assisted N-formylation of various aromatic and alkyl amines with formic acid under solvent-free conditions. Nano-MgO showed excellent catalytic properties and the reactions went to completion, within 1-2 min to give products in high yield (90-98%). The catalyst is recoverable quantitatively and re-cycled with almost consistent activity. This new nano catalyst has the advantages of higher yield, lower cost, reduced environmental hazards, and the procedure is highly convenient. Graphical Abstract: Nano-MgO was prepared and characterized by PXRD, SEM, BET and TEM analyses. It was used for the study of microwave-assisted N-formylation of various amines with formic acid under solvent-free condition.

N-Formylation of primary and secondary amines has efficiently been carried out at room temperature in excellent yields by using catalytic amount of sodium formate in formic acid under solvent-free conditions. The process is remarkably simple and environmentally benign.
A convenient procedure for the formylation of amines and alcohols using cyanomethyl formate
Deutsch,Niclas
, p. 1561 - 1568 (1993)
A simple metyod for the direct formylation of amines using cyanomethyl formate is described. The formylation succeeds in moderate to high yields under mild and neutral conditions. Thus, formamides 2a-f, 2i-m are obtained at room temperature. A chemoselective N-formylation is achieved in the case of ethanolamine. The formylation of nitroanilines and the O-formylation of alcohols only succeeds in the presence of a catalytic amount of imidazole leading to 2g,h and 3a-e, respectively.
Solvent- and catalyst-free N-formylations of amines at ambient condition: Exploring the usability of aromatic formates as N-formylating agents
Batuta, Shaikh,Begum, Naznin Ara
, p. 137 - 147 (2017)
A solvent- and catalyst-free N-formylation protocol has been developed for amines (1s–21s) where aromatic formates (1r–6r) were used as the N-formylating agents. The amine substrates include both primary and secondary aromatic amines (1s–19s) as well as aliphatic amine (20s) and a primary amide (21s). Structures of both the aromatic formate and amine components strongly influenced the rate of the reaction and yield of the N-formamide products. The reaction condition is mild and easy to operate. This protocol can be done smoothly under ambient conditions and gives high yield of formamide products. Furthermore, the present method cannot be applied for the formylation of thiol group (22s). This signifies its possible use for the chemoselective N-formylation of amine in the presence of thiol functionality.
