He also found that diaceto succinic ester reacts with compounds of the type NH 2 R(R = H, CH 3, OH, NHC 6 H 5, &c.) to form pyrrol derivatives CH3 CO CH CO 2 R, C(CH3) :C C02R A NH 2 R -?- - RN(CH 3 CO CH CO 2 R C(CH3) :C C02R By using compounds of the type NH 2 R and acetophenone acetoacetic ester C 6 H 5 CO CH 2.
Silicon nitrogen hydride, SiNH, is a white powder formed with silicon amide when ammonia gas (diluted with hydrogen) is brought into contact with the vapour of silicon chloroform at -10° C. Trianilino silicon hydride, SiH (NHC 6 H 5) 3, is obtained by the action of aniline on a benzene solution of silicon chloroform.
It is also formed by the action of sulphuretted hydrogen on the isocyanic esters, 2CONC 2 H 5 +H 2 S=COS+CO(NHC 2 H 5) 2, by the action of concentrated sulphuric acid on the isothiocyanic esters, Rncs H 2 O = Cos Rnh 2, Or Of Dilute Sulphuric Acid On The Thiocyanates.
Diazoamino benzene, C 6 H 5 N: N NHC 6 H 5, was first obtained by P. Griess (Ann., 1862, 121, p. 258).
C 6 H,N 2 NHC 6 H 6+2HC1+H NO 2 =2C6H5N2C1+2H20.
Diazoaminobenzene, C 6 H 5 N 2 NHC 6 H 61 crystallizes in golden yellow laminae, which melt at 96°C. and explode at a slightly higher temperature.
On the other hand, at about 240° C., the amine and ester react to form 13-anilidocrotonic ester, CH 3 C(NHC 6 H 5): CH COOC2H5r which yields y-oxy-a-methylquinoline (M.
