    • [1-(Ethoxycarbonyl)-1-cyclopentyl]triphenylphosphonium Bromide, [(C6H5)3PC(C4H8)(COOC2H5)]Br 
      Boys Mardones, Daphne; Araya Maturana, Ramiro; Gonzáles Campos, Oscar Cesar; Manríquez Castro, Víctor (1995)
      The crystal structure of the title phosphonium salt consists of a tetrahedral (C6Hs)P +C(C4HS)- (COOCH2CH3) cation and a Br- anion. The triphenylphosphonium group has P---C(phenyl) distances which are equal within ...
    • Crystal structure of 7-bromo-5,8-dihydroxy-4,4-dimethyl-4H-naphthalen-1-one 
      Mejías, Lorenzo; Caroli Rezende, Marcos; Sepúlveda Boza, Silvia; Araya Maturana, Ramiro; Boys Mardones, Daphne; Cassels Niven, Bruce; Manríquez Castro, Víctor (SOCIEDAD CHILENA DE QUIMICA, 1998-12)
      An X-ray diffraction study of the 7-bromo-5,8-dihydroxy-4,4-dimethyl-4H-naphthalen--1-one (1), obtained by bromination of 5,8-dihydroxy-4.4-dimethyl-4H-naphthalen-1-one with molecular bromine, gave unambiguous proof of its ...
    • Synthesis and reactivity of new trimethylplatinum(IV) complexes containing chiral Schiff bases as ligands: ... 
      Ramírez, Paola; Contreras, Raúl; Valderrama, Mauricio; Boys Mardones, Daphne (ELSEVIER, 2006-01-15)
      Reaction of the tetranuclear complex [PtIMe3](4) with the ligand (S)- and (R)-Ph2P(C6H4)CH=NC*H(Ph)Me in a 1:4 molar ratio yields the mononuclear neutral complexes in diastereoisomeric mixtures [PtIMe3{K-2-Ph2P(C6H4)CH=N ...
    • Yaretol, a norditerpenoid from Azorella madreporica 
      Loyola, Luis Alberto; Bórquez, Jorge; Morales, Glauco; San Martín Barrientos, Aurelio; Manríquez Castro, Víctor; Boys Mardones, Daphne; Darias, José (American Chemical Society, 2002-11)
      A new norditerpenoid, yaretol (1), was isolated from the whole plant of Azorella madreporica. The structure of 1 was established by one- and two-dimensional NMR techniques and confirmed by X-ray diffraction analysis.
