Synthesis and Crystal Structure of Overcrowded Non-photochromic Organometallic Fulgide
Pure E-isomer overcrowded organometallic fulgide 1 was obtained by using successive Stobbe condensations between ketones and succinate diester. Upon irradiation with UV light at (366 nm) it did not cyclise photochemically to the 1,8a-dihydronaphthalene derivative (1,8a-DHN) 8. The structure of 7 was confirmed by X-ray …
