A series of new 1-, 2-, and multi-substituted indenes has been synthesized and characterized. The reaction of indenyl lithium or 4, 7-dimethylindenyl lithium with alkenyl bromides yielded a mixture of 1-and 3-allylindene (1), 3-(3-buten-1-yl) indene (2), 3-(4- penten-1-yl) indene (3), 3-allyl-4, 7-dimethylindene (4), 3-(3-buten-1-yl)-4, 7-dimethylindene (5), as well as 3-(4-penten-1-yl)-4, 7-dimethylindene (6). The 2-substituted indenes 2- ...
