The preparation of (1RS,4RS)1-Methoxyspiro[bicyclo[2.2.2]oct-5-ene-2, 2'-[1',3 ']dithiolane] compound by a literature method was shown. The compound consists of a five-membered dithiolane ring with a methoxybicyclooctene spiro-fused at the 2-position. It was observed that the S atom of the dithiolane ring have electron-releasing properties, but the O atom of the methoxy group was electron-withdrawing, thereby influencing the bond lengths and angles of the dithiolane ring. The structure determination of the compound was undertaken to understand the effects of the methoxybicyclo-octene system and to compare the results with those foun . . .d in 1,2,3,4- tetrahydrocarbazole-1-spiro-2'-[1,3]dithiolane Daha fazlası Daha az
