An efficient protocol for the synthesis of selenated tetracyclic indoloazulenes I (R = H, Me, F; R1 = Me, n-Pr, n-Bu, Ph; R2 = H, OMe; R3 = H, OMe, Cl) was reported. The reaction of diorganyl diselenides R1SeSeR1 with mol. iodine in dichloromethane leads to the in situ formation of organo selenenyl iodide. The synthesis of selenylated tetracyclic indoloazulenes I through intramol. cascade cyclization has been achieved via organo selenenyl iodide and bisindole at room temperature under metal-free conditions in good yields. This study involved multiple reactions and reactants, such as 5-Chloro-2-(phenylethynyl)benzaldehyde (cas: 1186603-47-3Reference of 1186603-47-3).
5-Chloro-2-(phenylethynyl)benzaldehyde (cas: 1186603-47-3) belongs to organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Reference of 1186603-47-3
