cf. preceding abstract 1,4-Diethynyl-1,4-dihydroxy-2,5-cyclohexadiene was reduced to 1,4-diethynylbenzene (I), m. 95°, and 9,10-diethynyl-9,10-dihydroxy-9,10-dihydroanthracene to 9,10-diethynylanthracene (II), yellow needles changing at 86-88° to a brown-black nonmelting substance. As reducing agents SnCl2, Na dithionite, and TiCl3 were used. I and II are fluorescent and light-sensitive. I + HCHO + Et2NH gave a Mannich base, light yellow oil, b0.4 108-10°; HCl salt, m. 187-8°.
