Under solvent-free reaction conditions and in the presence of solid LiClO4 a novel and mild protocol for the one-pot, three-component synthesis of primary α-amino phosphonates from an aldehyde, hexamethyldisilazane and a trialkyl phosphite is described giving high yields and having short reaction times. The same products are obtained in very low yields, when the three-component reaction is carried out under microwave irradiation and in the absence of solid LiClO4. Examples of some prepared 1-aryl-N,N′-bis(arylidene)methanediamines are also described.

Triallylborane-amines adducts are effective stoichiometric allylating agents in the aminoallylation reaction of carbonyl compounds in methanol. Moreover, copper-catalyzed diastereoselective allylation of Ellman's imine was achieved with triallylborane-methylamine adduct.

Flash vacuum pyrolysis of arylmethylazides 7a-d gave 2,4-diazapentadienes 5a-d in high yield (76-92%). The thermal cyclization of 5a-d gave cis-imidazolines 1a-d, further heating or Swern oxidation of 1a-d gave dehydrogenated products, imidazoles 2a-d.
Microwave-assisted rapid and selective synthesis of cis- and trans-2,4,5-triarylimidazolines from aromatic aldehydes
Uchida, Hitoshi,Tanikoshi, Hirofumi,Nakamura, Shuichi,Reddy, Paidi Yella,Toru, Takeshi
, p. 1117 - 1120 (2007/10/03)
Microwave irradiation of a mixture of aromatic aldehydes and hexamethyldisilazane in the presence of a solid catalyst such as alumina afforded methanediamines which were efficiently converted to either cis- or trans-2,4,5-triarylimidazolines depending on the base used. A one-pot selective synthesis of cis- and transimidazolines from aromatic aldehydes was achieved under microwave irradiation.
Regioselective synthesis of cis- and trans-2,4,5-triarylimidazolines and 2,4,5-triarylimidazoles from available reagents

, p. 674 - 678 (2007/10/03)
Novel data were obtained concerning the reaction of aromatic aldehydes with ammonia. A preparative method for the synthesis of new substituted 1,3,5-triaryl-2,4-diazapenta-1,4-dienes was developed. These products are the starting reactants for syntheses of cis- and trans-2,4,5-triaryl-2-imidazolines and 2,4,5-triarylimidazoles.
