Barium amide

Amina.tlon, 2-Antinoquinoline [580-22-3] is obtained from quinoline in 80% yield by treatment with barium amide in Hquid ammonia (19). This product, as weU as 3-aminoquinoHne [580-17-6] and 4-antino quinoline [578-68-7], maybe obtained through nucleophilic substitution of the corresponding chloroquinolines with ammonia. 

Even a cursory reading of Chapter 3 of the previous volume/ dealing with alkaline earth diorgano amides, shows that detailed information on their preparation, structure and reactivity was quite sparse. For example, there were no data available for strontium or barium amide derivatives and there was just one structure of a complex related to a calcium amide - that of [(thf)3Ca( AIH j(. - in which calcium was incorporated as part of an...

Aminoquinoline is obtained from quinoline in 80% yield by treatment with barium amide in liquid ammonia. 

These compounds are less thermally and kinetically stable than either their unsubstituted or their decaphenylmetallocene analogues they decompose near 200°C in the solid state (cf. 350°C for the decaphenylmetallocene derivatives [M(C5Ph5)2] M = Ge, Sn, Pb47) and in minutes in THF at room temperature.46 A yellow barium complex has been prepared by the reaction of two equivalents of C5Ph4H2 with the soluble barium amide [Ba N(SiMe3)2 2(thf)2] in THF or toluene [Eq. (3)].41...
