CODEN: ACSEBH. ISSN: 1600-5368. DOCUMENT TYPE: Journal; (online computer file) CA Section: 75 (Crystallography and Liquid Crystals) Section cross-reference(s): 78 Crystals of the title complex are monoclinic, space group P21/c, with a 11.042(2), b 9.487(2), c 17.796(2) ?,, b 95.635(10)°; Z = 4, dc = 1.686; R = 0.032, Rw(F2) = 0.089 for 4267 reflections. The central Pd atom has a distorted cis-planar four-coordination geometry defined by two O atoms of a 1,2-benzenediolate dianion and two N atoms of a 2,2'-biquinoline ligand. The overall structure of the complex is not planar, with a dihedral angle of 136.23(8)° between the quinoline and benzenediolate mean planes.

PRIORITY: IT 76-19735 30 Jan 1976. DOCUMENT TYPE: Patent CA Section: 25 (Noncondensed Aromatic Compounds) 1,2-Benzenediols were methylenated with CH2Cl2 in the presence of Bu4NBr or (C16H33)Bu3PBr to give methylenedioxy derivs. of benzenes. Thus, 1,2-C6H4(OH)2, 4-MeC6H4(OH)2-1,2, and 3,4-(HO)2C6H3CHO gave I, II, and III, resp.
