2- butylphosphonic acid

Organophosphonates are isoelectronic with organotrisiloxides. Like zinc siloxides and zinc siloxanes, zinc phosphonates are actively investigated as porous materials, for applications in catalysis, as molecular sieves, and for electronic devices. Dimethyl- and diethylzinc reacted with / //-butylphosphonic acid in THF solution to furnish,... [Pg.368]

One methyl group in the dimethyl derivatives 406a (R = R7 = Me) may be also cleaved by the reaction with f-BuPO(OH)2240. According to the X-ray data, the t-butylphosphonic acid ligand in the resulting nonsymmetrically substituted stannocane [r-BuP(Oj(OI I)0 MeSn(CH2CH2( l 12)2 NMe 408 coordinates with the tin center only via the oxygen atom. [Pg.1122]

It is possible to use ancillary ligands in addition to phosphonic acids in building up nanosized cluster compounds of late transition metal ions. Thus, the reaction of CuCl2 with tert-butylphosphonic acid in the presence of 3,5-dimethylpyrazole affords a dodecanuclear copper phosphonate with an interesting cage structure,3 Similarly, large vanadium phosphonate clusters with up to 18 vanadium atoms have been assembled from phosphonic acids.35... [Pg.362]

SAMs of allgrlphosphonic acids (butylphosphonic acid, octylphosphonic acid, undecylphosphonic acid and octadecylphosphonic acid) on native niekel oxide allow substrates to be functionalized easily. Monolayer formation has been investigated by diffuse reflectance Fourier transform infrared spectroscopy, non-contact mode atomic force microscopy, contact angle measurements and matrix-assisted laser desorption ionization mass spectrometry. Cyclic voltammetry and electrochemical impedance spectroscopy studies showed that the monolayer increased surface resistance to oxidation. [Pg.291]

Severin and co-workers have demonstrated that borophosphonate cages of the general formula [f-BuP03BR]4 (376) could be obtained in good to excellent yields by condensation of te/t-butylphosphonic acid with boronic acids (Scheme 131). ... [Pg.306]

The reaction of diphenyl methylphosphonate with lithium alkoxides gives phenyl alkyl methylphosphonates even with hindered alcohols and, in the case of chiral alcohols, with high diastereoselectivity at phosphorus. [Hydroxy(pho-sphoryloxy)X, iodo]benzenes 289, prepared from reactions of iodosobenzene with phosphonic or phosphinic acids react with ketones, esters or phenyl acetylene to give esters 290. Racemic l-hydroxy-4-(3-phenoxyphenyl)butylphosphonate diethyl ester undergoes stereoselective acetylation in the presence of a lipase to... [Pg.136]
