Reporting strategy

Although the majority of allylic etherification reactions have primarily utilized allylic carboxylates or carbonates as electrophiles (and occasionally allylic chlorides), the use of allylic alcohols for this transformation would be more desirable from a practical standpoint. Reported strategies involving Pd catalysis include the use of P(OPh)3 as the ligand197 and Ti(OPf)4198 as an additive for the in situ activation of the hydoxyl group (Equation (49)).199... 

The fourth reported strategy approached 1 in a five-step sequence starting from acetylcyclopropane (10) via 11,12,15, and 14 [9] (Scheme 2). 

The reported strategies utilized in DNA sensing include (1) sequence-specific hybridization processes based on the oxidation signal of most electroactive DNA bases, guanine and adenine [13,24] or (2) quasi-specific detection of small molecules capable of binding by intercalation or complexation with DNA, such as metal coordination complexes, antibiotics, pesticides, pollutants, etc. [17,18] or in the presence of some metal tags such as gold, silver nanoparticles, etc. [23,50,51]. 

The use of column with superficially porous packing materials based on silica particles with nonporous cores is the most recently reported strategy for improving chromatographic performance. This technology, originally developed by Kirkland in the 1990s to limit diffusion of macromolecules into the pores [85], became commercially available in 2007 [86], In comparison with totally porous particles of similar diameters, the both A and C term of the Van Deemter curve are reduced [87, 88],...

The model for an analysis and reporting strategy presented emphasizes the importance of a structured plan of work in combination with team s commitment, in the attempt to complete participation in the OPCW proficiency-testing scheme successfully. However, teamwork among laboratory staff may not be enough successful participation requires full support from management too. After all, management must understand that participation requires full devotion from the laboratory other tasks preferably have to wait for a later point in time. 

A typical ruthenium alkylidene catalyst (Figure 5) can be anchored through the neutral ligand (phosphine or carbene), the anionic ligand (where X is usually a phenolate), or even the alkylidene (where R = phenyl), and Barrett and Hoveyda have reported strategies. However such work is in its infancy and further development is required before these techniques become commercially viable. 

Before 1995, there were three different reported strategies to produce cyclic bisbibenzyls, which led to the synthesis of 12 natural products. Individual strategies differ mainly in the way the macrocyclic ring is closed [435]. 

The tables in this appendix are reprinted from a previous National Research Council report, Strategies to Protect the Health of Deployed U.S. Forces Force Protection and Decontamination.1 They provide brief descriptions of both chemical agents (Tables B.l through B.3) and biological agents (Tables B.4 through B.7), as follows ...

The steps needed to move towards expanded reporting are identified. These will include not only environmental performance but also social and ethical matters within the overall umbrella of sustainability. The chemicals industry is unique in that it has established an industry-specific standard for environmental reporting, and the case for other industries following this lead is discussed. Also, the role of the internet in future reporting strategy is considered briefly. 

The glycopeptide assembly process relies mainly on the established methods of solid-phase peptide chemistry. However, the synthetic strategy has to be adapted to accommodate the chemical sensitivities of the carbohydrate moiety, whether the saccharide is present during chain elongation or the carbohydrate moiety is incorporated after chain assembly is complete. Of the different reported strategies for the preparation of glycopeptides [12],...
