The Isomerization of Triphenylmethyl Isocyanide: Evidence for a Cationic Chain Mechanism in Polar Solvents

CHIMIA, 1986
Triphenylmethyl isocyanide (1) isomerizes to triphenylmethyl cyanide (2) in non-polar solvents at 200-250 °C by a sigmatropic 1,2-rearrangement. To account for the high rate of rearrangement in polar solvents (e.g.

[4 + 2]-Cycloadditions to 1 '-Phenyl-Substituted 3-Vinylindoles with N-Phenylmaleimide: An Access to New [a]Anellated Carbazole Derivatives

CHIMIA, 1987
The AlCl3-catalyzed [4 + 2]-cycloaddition of T-phenyl-substituted 3-vinylindoles with N-phenylmaleimide gives rise to new anellated carbazole derivatives with a high endo-preference.

Synthese von Bis(sulfinylamido)selen OSN–Se–NSO

CHIMIA, 1987
Se(NSO)2 is formed in good yields from Se2Cl2 and (CH3)3SiNSO dissolved in dichloromethane or hexamethyldisiloxane. Structural, spectroscopic, and physical data for the new selenium pseudohalide are presented.
