Some of the major advantages of this protocol are: good yields, the involvement of a less-expensive and non-toxic catalyst, mild and solvent-free reaction conditions and also tolerance towards other functional groups present in the substrates. Eighteen examples are described, highlighting the substrate scope of the reaction.</p>10aaldehydes10aalkyl phosphite10aalpha-amino phosphonates10aamines10abismuth nitrate pentahydrate10asynthetic methods1 aBhattacharya, Asish, K.1 aKaur, Tanpreet  uhttps://library.ncl.res.in/content/efficient-one-pot-synthesis-alpha-amino-phosphonates-catalyzed-bismuth-nitrate-pentahydrate
