Ruthenium complexes with vinyl, styryl, and vinylpyrenyl ligands: a case of non-innocence in organometallic chemistry.
We herein describe a systematic account of mononuclear ruthenium vinyl complexes L-{Ru}-CH=CH-R where the phosphine ligands at the (PR'3)2Ru(CO)Cl={Ru} moiety, the coordination number at the metal (L = 4-ethylisonicotinate or a vacant coordination site) and the substituent R (R = nbutyl, phenyl, 1-pyrenyl) have been varied. Structures of the enynyl complex Ru(CO)Cl(PPh3)2(eta1:eta2-nBuHC=CHCCnB...
متن کاملThe toxicity of dimethyl sulphoxide (DMSO) for the dog, pig, rat and rabbit.
Dimethyl sulphoxide (DMSO) was tested for oral toxicity in rats and dogs, and dermal toxicity in rabbits and pigs. Oral administration was by gastric intubation as a 50% equeous solution, 5 days/week at levels equivalent to 9.0, 3.0 or 1.0 ml undiluted DMSO/hg/day. For dermal application 50% and 90% equeous solutions were used to give levels equivalent to 8.1, 4.5, 2.7 or 1.5 ml DMSO/hg/day, as...
متن کاملPlatinum Co-ordination Complexes in Cancer Chemotherapy
Following its widespread adoption into clinical practice in the early 1970s the drug cispiatin (cis-diamminedichloroplatinum(II), cis[PrClfiH J2]) has improved substantially the response rate5 in a number of malignant conditions, particularly testicular and ovarian cancer. However, the clinical utility of the drug is limited by its toxic side effects. The most significant of these is kidney tox...

interactions which can be done when more structural information is available, but they do provide order of magnitude estimates of interaction strengths. Evidently, considerable rearrangement of charge driven by reduction significantly raises the effective dielectric. It seems likely that centres S-2 and FR-2 are apparently low-potential clusters merely because they are the middle clusters in th...
متن کاملUse of Dimethyl Sulphoxide for Preserving Corneal
SINCE it was discovered by Polge, Smith, and Parkes (1949) that living cells could be protected during freezing and thawing by adding glycerol to the storage medium, various substances and methods have been used in an attempt to achieve better results (Fleming,: 1952; Eastcott, Cross, Leigh, and North, 1954; Lovelock, 1954). We have been concerned with retaining the viability of corneal tissue ...
