The unique properties of ethers (i.e., that they are strongly polar, with nonbonding electron pairs but no hydroxyl group) enhance the formation and use of many reagents. For example, Grignard reagents cannot form unless an ether is present to share its lone pair of electrons with the magnesium atom.SDS of cas: 2235-01-0

Sulu, Mustafa;Venanzi, Luigi M. published 《Acetalization and transacetalization reactions catalyzed by ruthenium, rhodium, and iridium complexes with {2-[{Bis[3-(trifluoromethyl)phenyl]phosphino}methyl]-2-methylpropane-1,3-diyl}bis[bis[3-(trifluoromethyl)phenyl]phosphine] (MeC[CH2P(m-CF3C6H4)2]3)》 in 2001. The article was appeared in 《Helvetica Chimica Acta》. They have made some progress in their research.SDS of cas: 2235-01-0 The article mentions the following:

The complexes [RhCl(3-n)(MeCN)n(CF3triphos)](CF3SO3)n (n = 1 or 2; CF3triphos = MeC[CH2P(m-CF3C6H4)2]3) and [M(MeCN)3 (CF3triphos)](CF3SO3)n (M = Ru, n = 2; M = Ir, n = 3) are catalyst precursors for some typical acetalization and transacetalization reactions. The activity of these complexes is higher than those of the corresponding species containing the parent ligand MeC[CH2P(C6H5)2]3(Htriphos). Also the complexes [MCl3(tripod)] (tripod = Htriphos and CF3triphos) are active catalysts for the above reactions. The complex [RhCl2(MeCN)(CF3triphos)](CF3SO3) catalyzes the acetalization of benzophenone. To complete the study, the researchers used Dimethoxydiphenylmethane (cas: 2235-01-0) .
