“…Loizou et al 294 prepared cyclopentadienyldinitrosyl(trifluoromethyl)chromium(0) CpCr(NO) 2 CF 3 (71%), and cyclopentadienyldinitrosyl(trifluoromethyl)molybdenum(0) CpMo(NO) 2 CF 3 (44%) via the reaction of Cd(CF 3 ) 2 ·monoglyme with the corresponding chlorides at 65 °C. Ludovici et al 295 achieved nearly quantitative yields of C n F 2n+1 NO ( n = 1, 2, 3, 6) by the reaction of NOCl with Cd(C n F 2n+1 ) 2 ·monoglyme. Daniele et al 296 synthesized La(OTf)(OC 6 H 3 -2,6-Me 2 ) 2 (glyme) [glyme = triglyme or tetraglyme] derivatives through reactions between lanthanum triflate adducts La(OTf) 3 (glyme) and 2 equiv.…”

Glymes, also known as glycol diethers, are saturated non-cyclic polyethers containing no other functional groups. Most glymes are usually less volatile and less toxic than common laboratory organic solvents; in this context, they are more environmentally benign solvents. However, it is also important to point out that some glymes could cause long-term reproductive and developmental damages despite their low acute toxicities. Glymes have both hydrophilic and hydrophobic characters that common organic solvents are lack of. In addition, they are usually thermally and chemically stable, and can even form complexes with ions. Therefore, glymes are found in a broad range of laboratory applications including organic synthesis, electrochemistry, biocatalysis, materials, and Chemical Vapor Deposition (CVD), etc. In addition, glyme are used in numerous industrial applications, such as cleaning products, inks, adhesives and coatings, batteries and electronics, absorption refrigeration and heat pumps, as well as pharmaceutical formulations, etc. However, there is a lack of comprehensive and critical review on this attractive subject. This review aims to accomplish this task by providing an in-depth understanding of glymes’ physicochemical properties, toxicity and major applications.

“…While methods for the preparation of nitroso arenes , and α-bromo and α-chloro nitroso alkanes are well developed, approaches to fluorinated aliphatic nitroso compounds are scarce. In particular, perfluorinated nitroso alkanes can be obtained by electrophilic nitrosation of perfluorinated mercury, cadmium, and silicon reagents . Several other specific reactions involving harsh conditions and affording polyfluorinated nitroso alkanes have been reported .…”

“…23 In some of the syntheses, the toxic (CF 3 ) 2 Cd compound has been employed as the transfer reagent with products being isolated in low yields. 24 We now report a simple and efficient method to prepare perfluoronitrosoalkanes in very good yield. The reaction of (perfluoroalkyl)trimethylsilane (Me 3 SiR f , R f = CF 3 , C 2 F 5 ,) with nitrosyl chloride in the presence of caesium fluoride led to the formation of perfluoronitrosoalkanes in > 90% yields.…”
