Handling Air-Sensitive Reagents

Suppliers of air-sensitive reagents usually dispatch them securely sealed under nitrogen. They also supply equipment and literature for handling not only air-sensitive chemicals but also hazardous chemicals. All these chemicals should be handled by experienced technicians or third year undergraduates, following the instructions sent with the equipment.

When handling air sensitive reagents always think ahead, and design the whole sequence of events you intend to follow so that air never comes into contact with the reagent.

The solution of methyllithium was conveniently handled using techniques for the manipulation of air-sensitive reagents. ... 

Handling, Storage, and Precautions NB-Enantrane is an air-sensitive reagent and must be handled under an inert atmosphere. Use in a fume hood. 

A low-temperature electrochemical oxidation system for the generation of cation pools is shown in Figure 5.6. The DC power supply is not very expensive, and the reactions can be easily conducted with normal laboratory techniques that are used for the handling of air-sensitive reagents at low temperatures.

There is a cost associated with the effort needed to prepare these nanostructured materials building blocks must be found and suitably functionalized tailored linking reagents are required air sensitive handling procedures developed and byproducts carefully removed. It is therefore appropriate to ask, has the effort and expense lead to new and better catalysts ... 

Recent developments in reaction techniques which include handling of air-sensitive and moisture-sensitive compounds new chromatographic procedures phase transfer catalysis and solid support reagents. 

Handling, Storage, and Precautions guidelines for handling air-and moisture-sensitive reagents should be followed. The pure reagent is described as an irritant. 

Handling, Storage, and Precautions the ligand is stable when stored under an inert atmosphere. The phosphine is air-sensitive and will oxidize to the phosphine oxide in the presence of oxygen or other oxidizing reagents. 

Reagents which are neither sensitive to the atmosphere nor toxic are normally stored in ordinary bottles on the shelf and they are usually easy to handle. However, if you are going to use this type of reagent for reactions with air sensitive materials, they must also be dry and be stored with the atmosphere excluded It is no use carefully setting up an anhydrous reaction, then adding a reagent straight from an unsealed bottle on the shelf. 

This compound has also been prepared by the reaction of MnX(CO)5 (X = Cl, Br) and CgHgSH related complexes Mn2(ji.-SR)2(CO)g (R = CH3, C2H5, A1-C4H9) have been made by reaction of MnH(CO)s and RSSR. The yield of product by the former route is not good (and the procedure has not been widely used) because it is difficult to set conditions so that Mn4( i-SPh)4(CO)j2 is not obtained concurrently. The latter procedure requires a reagent, MnH(CO)j, which is air sensitive and less easily handled.
