New route to synthesis of unexpected 1,5-bis(1-benzofuran-2-yl) pentane-1,5-dione derivatives: Their structure determination with spectroscopic and X-ray methods

A facility and one-step process has been explored for the first time for the preparation of 1,5-bis(1-benzofuran-2-yl)-1,5-diones and the structures of synthesized compounds were identified by 1H, 13C-NMR, HSQC, HMBC and X-Ray.122
