Ueber Schiff'sche Basen

Abstract: and S t r e c k e r l ) und dae Anhydroformaldehydanilin vom Schmelepunkt 140° von Tollensa) und Pratesi3).Ueber die Moleculargriisse dieser Verbindungen war bisher nichts Sicheres bekannt. Wir fanden mittels der Rao ult'schen Methode, dass dem Anhydroformaldehydanilin vom Schmelepunkt 140° die dreifache Formel, dem Anhydrovaleraldebydauilin und dem Acetaldehydanilin die zweifache Formel zukommt. Wiihrend aber &a Anhydroformaldehydanilin und das Anhydrovaleraldehydanilin sich in ihren Reactionen wie die einfac… Show more

“…Tertiary aliphatic and aro matic aldehydes at room temperature react readily and nearly quantitatively with amines to give the imines without the aid of catalysts [la]. Secondary aliphatic aldehydes readily form imines with amines with little or no side re actions [5]. The use of low temperatures and potas sium hydroxide favors the formation of the imine product [4a, b].…”

“…Benzaldehyde substituents such as nitro, dialkylamino, hydroxyl, methoxyl, or halo have been used [7a-c]. The crude product is added to alcohol [5] in order to induce crystal lization [6]. 51°-52°C, is prepared in 87% yield by adding 1.0 mole of aniline to 1.0 mole of benzaldehyde at room temperature in the absence of a solvent.…”

“…Ever since Laurent and Gerhard [1] synthesized the first organic imine by condensation of benzylaldehyde with aniline, numerous investigations deal with this class of compounds, also known as Schiff's bases [2][3][4][5]. Schiff bases are an important class of ligands in coordination chemistry and find extensive application in different fields.…”
