Magnesium bis(hydridotriphenylborate), isolated as a solvent-separated ion pair [Mg(thf)6][HBPh3]2, effectively catalyzed the hydroboration of several unsaturated substrates including CO2.

This paper argues that innovation can be best understood as an information process which is then concretized as a product that meets demand. Two very different firms, Canon Inc. and Apple Computer Inc., are used as case study illustrations. Innovation does not proceed through logical deduction, but rather is furthered by the use of metaphors and analogies. The bureaucratic and staid structures ...

The observation of Manchot? that sodium pentacyano-ammineferroate2 I absorbs oxygen has led Baudisch and his coworkers3 to study the catalytic action of this salt, as well as of its water analogue II, in the oxidation of pyrimidines and purines. The present authors have previously reported in this journal4 on the nature of the oxidation products obtained. In the present paper the problem is con...

The Cover Feature shows a concerted carbonyl hydroboration mechanism involving Mg−O, B−H, and C=O bonds. Homoleptic magnesium alkoxides catalyze ketone with turn-over frequency (TOF) reaching up to 59,400 h−1 exhibit exceptional functional group tolerance. This TOF is so far the best observed in main catalyst without involvement of metal hydride intermediate. newly proposed finds general applic...

background: hypomagnesaemia is one of the main side effects of cisplatin-based chemotherapy regimens in cancer patients. the aim of the current investigation was to evaluate the effect of oral magnesium oxide (mgo) supplementation on cisplatin-induced hypomagnesemia. methods: this parallel-randomized controlled, open label trial was conducted in a hospital of iran university of medical sciences...

objectives: this study was designed to assess nutritional and biochemical factor of magnesium in postmenopausal osteoporotic women. methods & materials: the population of this analytical cross- sectional study, was 60 postmenopausal osteoporotic women ,referred to rheumateology clinic of tabriz. nutritional intake was determined by 3 day food recall and food frequency questionnaire، individual ...

In order to improve the yield of BN nanotubes prepared by ball milling annealing method, a small amount magnesium was used as catalyst synthesized boron nitride nanotubes. The results showed that with high yield, purity and uniform size were synthesized. morphology BNNTs is bamboo-like cylinder-shaped. diameter them about 50 150 nm most are 100nm. length dozens microns. existence end particles ...
