Selective Dealkenylative Functionalization of Styrenes via C-C Bond Cleavage.
As a readily available feedstock, styrene with about 25 million tons of global annual production serves as an important building block and organic synthon for the synthesis of fine chemicals, polystyrene plastics, and...
Catalytic meta-selective C–H functionalization to construct quaternary carbon centres
A catalytic meta-selective C–H functionalization of 2-phenylpyridines using a range of tertiary halides is described. The protocol is simple to perform and uses commercially available reagents to construct challenging quaternary...
On the appearance of nitrite anion in [PdX(OAc)L<sub>2</sub>] and [Pd(X)(C∧N)L] syntheses (X = OAc or NO<sub>2</sub>)
Pd 3(OAc) 5NO 2, an impurity in "Pd(OAc) 2" {formally Pd 3(OAc) 6}, emerges as a serious issue in the synthesis of pure Pd II complexes derived from Pd(OAc) 2, for example in our C-H activation precatalyst, Pd(OAc) 2(pip) 2 (pip...
Modular and Selective Arylation of Aryl Germanes (C-GeEt3 ) over C-Bpin, C-SiR3 and Halogens Enabled by Light-Activated Gold Catalysis.
Selective C sp 2 -C sp 2 couplings are powerful strategies for the rapid and programmable construction of bi- or multiaryls. To this end, the next frontier of synthetic modularity will likely arise from harnessing the...

Catalytic C(sp3)-H bond activation in tertiary alkylamines.
The development of robust catalytic methods to assemble tertiary alkylamines provides a continual challenge to chemical synthesis. In this regard, transformation of a traditionally unreactive C-H bond, proximal to the nitrogen...
MAC Protocol Analysis for Wireless Sensor Networks
In wireless sensor networks, MAC protocol is used to achieve efficient, fair and balanced allocation of wireless channel resources and access control of nodes in the network, and to control the communication process of nodes in...

Modeling and Optimizing Tsunami UDP Protocol
OPTIMUM study protocol
INTRODUCTION: Combination vaccines containing whole-cell pertussis antigens were phased out from the Australian national immunisation programme between 1997 and 1999 and replaced by the less reactogenic acellular pertussis (aP)...
Group Size and Matching Protocol in Contests
We investigate the effects of group size and matching protocol in Tullock contest experiments. In a 2x2 factorial design we implement partner and random stranger matching protocols in contests between two and between three...
Circulating vitamin C and digestive system cancers
BACKGROUND & AIMS: Vitamin C is an antioxidant with a potential role in the prevention of digestive system cancers, but there is yet no consensus whether vitamin C has a causal role in these cancers. The aim of this study was to...
Massive blood loss protocol 'Code Red' at Papworth Hospital
AIM: To investigate if the massive blood loss protocol 'Code Red' at a specialist cardiothoracic hospital was activated according to local and national guidelines by a closed loop audit. METHODS: Electronic and paper patient...
Group Size and Matching Protocol in Contests
We investigate the effects of group size and matching protocol in Tullock contest experiments. In a 2x2 factorial design we implement partner and random stranger matching protocols in contests between two and between three...
Aliphatic C–H activation with aluminium trichloride–acetyl chloride
The functionalisation of decalin by means of an “aliphatic Friedel–Crafts” reaction was reported over fifty
years ago by Baddeley et al. This protocol is of current relevance in the context of C–H activation and
here we...
The United Kingdom Childhood Cancer Study
An investigation into the possible causes of childhood cancer has been carried out throughout England, Scotland and Wales over the period 1991-1998. All children known to be suffering from one or other type of the disease over...
