Nucleophilic addition of phosphinic acid, phosphites, sodium dialkyl phosphites, phosphoramidites, phosphinites, and phosphonites to highly polarized or cationic fluorophores, followed by oxidation, results in new “PONy” dyes with auxochromic phosphinate, phosphonate, or phosphonamidate groups. The reaction was applied to a wide variety of coumarins, (thio)pyronins, and N-alkylacridinium and 5,6-dihydrobenzo[c]xanthen-12-ium salts as well as a meso-chlorinated BODIPY to provide compact dyes with red-shifted absorption and emission bands and Stokes shifts up to 8200 cm-1.

Reaction of dichlorotetrakis(dmso)ruthenium(II) with methoxydiphenylphosphane in refluxing methanol gave dichlorotris-(methoxydiphenylphosphane)ruthenium(II) which dimerizes. The structure of the dimer was established by NMR and X-ray diffraction analyses; this ruthenium complex catalyzed the oxidation of alcohols by N-methylmorpholine oxide.

The new Cp*Ru(II) (Cp*: pentamethylcyclopentadienyl) complexes Cp*(dab-R)RuCl, [Cp*(dab-R)(MeCN)Ru][PF6] (dab-R: RNCH-CHNR; R: iso-propyl, mesityl), and [Cp*(cod)(MeCN)Ru][PF 6], are synthesized in high yields by reacting the corresponding alpha-diimine or 1,5-cyclooctadiene with [Cp*RuCl]4 and [Cp*(MeCN)3Ru][PF6], respectively. The alpha-diimine ligands are strongly bonded to the ruthenium centre as shown by the subsequent formation of the alkynyl derivatives Cp*(dab-R)RuCCR?

Thermolysis of the phosph(V)oles in the solid state, in suspension, or in solution, gives the ‘phosphole dimer’ (6) via dimerisation of the phosphinimine (7).This species, generated from the phosph(V)ole (3), or from the dimer (6), may be trapped by carbonyl compounds (aldehydes, ketones, or formamides) to give the phosphinates (8).Reaction with p-nitrobenzaldehyde converted the phosph(V)ole (3) into the benzoxazole (13).

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 4020-99-9, you can also check out more blogs about4020-99-9
