as well as the thiating Lawesson and Japanese reagents were studied. Elemental analysis and spectroscopic measurements were in good accord with the structures postulated for the new products. The antitumor activities of certain selected new compounds were screened, in vitro, against a panel of five (liver; HepG2; breast; MCF-7; lung; A549; colon; HCT116; and prostate PC3) human solid tumor cell lines

2-Substituted 3-amino-3-(methylthio)acrylonitriles cyanoketene S,N-acetals are synthesized by two convenient methods. The imino esters of their hydrochloride salts are found to be good starting materials for the synthesis of 4-substituted 3,5-diaminopyrazoles and 2,5-disubstituted 1,3,4-oxadiazoles.

Abstract 1,2-Bis(2-pyridyl)ethane-1,2-dione was allowed to react with different phosphorusnucleophiles. Treatment of the 1,2-bis(2-pyridyl)ethane-1,2-dione with the active phosphacumulene ylides, (N-phenylimino)-, and (2-oxovinylidene)-triphenylphosphorane afforded the phosphanylidene–cyclobutylidenes. On the other hand, its reaction with hexaphenylcarbodiphosphorane gave the oxaphosphetane and the phosphanylidene

The thermal redistribution of P4S10 with (RS)3PS (R = alkyl or aryl) generates metaphosphorotrithioic esters (RSPS2)2 and relatively smaller amounts of symmetrical [(RS)2P(S)]2S as ‘middle’ and ‘end’ species respectively. Reacting P4S10 with thiols affords similar mixtures. With dithiols HS(CH2)nSH (n= 2 or 3), no ‘middle’ compound was obtained but only ‘end’ and ‘ortho’ derivatives, chiefly [AS2P(S)]2Y
P 4 S 10与(RS)3 PS(R =烷基或芳基)的热重分布产生偏磷酸三硫代酸酯(RSPS 2)2和相对少量的对称[(RS)2 P(S)] 2 S作为“中间” '和'end'物种。P 4 S 10与硫醇反应可得到相似的混合物。使用二硫醇HS(CH 2)n SH(n = 2或3),没有得到“中间”化合物,只有“端”和“邻”衍生物,主要是[AS 2 P(S)] 2 Y(A =亚烷基) ,Y分别为–S–或–SAS–)。
