Keywords: 2,5-dihydroxy-1,4-quinone; cyclic voltammetry; phoshine; phosphinyl; X-ray structures EN 2,5-dihydroxy-1,4-quinone cyclic voltammetry phoshine phosphinyl X-ray structures 531 541 11 07/18/22 20220701 NES 220701 1 Introduction Coordination complexes built around the structural motif of 2,5-bis(phosphine) I p i -hydroquinone are relatively rare. SP 31 sp P NMR (C SB 6 sb D SB 6 sb ): I i = 73.3 (s). 4.3.4 Syntheses of 2,5-bis(diphenylphosphinyl)-3,6-hydroquinone (4a) and 2,5-bis(diisopropylp... Both compounds were synthesized by the same procedure, thus a detailed description of only one of them ( B 4a b ) is provided. Reported herein are syntheses and investigations for two of such compounds, 2,5-bis(diphenylphosphinyl)-3,6-dihydroxy-quinone ( B 4a b ) and 2,5-bis(diisopropylphosphinyl)-3,6-dihydroxy-quinone ( B 4b b ) (Figure 2). Thus, crystals of 2,5-dihydroxy-1,4-quinone and 2,5-dihydroxy 3,6-dichloro-1,4-quinone contain I intermolecular i hydrogen bonding between hydroxy groups and oxygens of quinone functionalities [[28]].
