Triazole derivatives R 0280Amidrazones in the Synthesis of 1H-1,2,4-Triazoles. -A convenient one-step procedure for the synthesis of various indanylidenetriazoles (III) via reaction of amidrazones (I) with (indanylidene)malononitriles (II) is reported. -(ALY*, A.

2,3-Diphenylcyclopropenone (1) reacts with N-imidoylthioureas 2a–e to form the pyrimidin-4(3 H)-ones 5a–e. The reaction mechanism can be described as due to stepwise addition accompanied by elimination of phenyl isothiocyanate.

Reaction of 4.5.12.13tetraki»(bromomethyl)[2.2]paracyclophane (6) with methane and p -toluenesulfonamide results In formation of dlhydrobenzo[c ]furanophane (4); however the desired Isolndolophane 3 was not formed. Formation of 4 was supported by the Interaction of 4.5.12.13tetrakls(hydroxymethyl)[2.2]paracyclophane (2) with -toluenesuHonic acid. On the other hand, Interaction of 6 with some aromatic amines gave the corresponding [2.2]lsolndollnophane derivatives 8a-f. Charge-transfer complexes of 8a-f (donors) with tetracyanoethylene (TONE), chloranil (CHL), 2-dlcyanomethylene-1,3-lndanedk>ne (CNIND), and 2,3-dlchloro-5,8-dlcyanobenzoqulnone (DDQ) as -acceptors have been studied spectrophotometrlcally.Unt* 1951 isoindole (1) was not prepared (1). Since that time there have been many reports of successful synthesis of isoindole and its derivatives. 1,2-Bls(bromomethyl)benzenes have
