Noncentrosymmetric films are fabricated by using multilayers containing alternating monolayers. One monolayer contains chromophores with high second-order optical susceptibiUty and the other having no nonlinear optical properties (190). The LB technique has also been appHed to fabricate noncentro symmetric stmctures having pyroelectric properties (191). Multilayered LB films incorporating charge-transfer salts (CT salts such as TTF, TCNQ) as central groups have been prepared that display electrical conductivity comparable to that of not only pure crystals of the CT salts, but also metals (192). Even superconductivity has been observed in LB films containing the central group metal-bis-(4,5-dimercapto-l,3-dithiole-2-thione), where the metal is Ni or Au. LB film-based field-effect transistors have been fabricated that exhibit current—voltage characteristics typical of inorganic (eg. Si-based) transistors (192).  [c.208]

After the umpolung of an aldehyde group by conversion to a l,3 dithian-2-ide anion (p. 17) it can be combined with a carbonyl group (D. Seebach, 1969, 1979 B.-T. GrO-bel, 1977 B). Analogous reagents are tosylmethyl isocyanide (TosMIC), which can be applied in the nucleophilic formylation of ketones (O.H. Oldenziel, 1974), and dichloromethyl lithium (G. KObrich, 1969 P. Blumbergs, 1972 H. Taguchi, 1973),  [c.51]

Esters. The monoisobutyrate ester of 2,2,4-trimethyl-1,3-pentanediol is prepared from isobutyraldehyde ia a Tishchenko reaction (58,59). Diesters, such as trimethylpentane dipelargonate (2,2,4-trimethylpentane 1,3-dinonanoate), are prepared by the reaction of 2 mol of the monocarboxyhc acid with 1 mol of the glycol at 150—200°C (60,61). The lower aUphatic carboxyHc acid diesters of trimethylpentanediol undergo pyrolysis to the corresponding ester of 2,2,4-trimethyl-3-penten-l-ol (62). These unsaturated esters reportedly can be epoxidized by peroxyacetic acid (63).  [c.374]

Isobutyraldehyde also undergoes consecutive aldol and Tischenko condensations to give 2,2,4-trimethyl-l,3-pentanediolmonoisobutyrate [25265-77-4] (Texanol, Filmer IBT), alternatively prepared by the esterification of TMPD with isobutyric acid.  [c.378]

Tetracyanoquinodimethane [1518-16-7] (5), 2,2 -(2,5-cyclohexadiene-l,4-diyhdene)bispropanedinitrile (TCNQ), is prepared by condensation of 1,4-cyclohexanedione with malononittile to give l,4-bis(dicyanomethylene)cyclohexane [1518-15-6] which is oxidized with bromine (31).  [c.404]

Such calculations have been performed by Takayanagi et al. [1987] and Hancock et al. [1989]. The minimum energy of the linear H3 complex is only 0.055 kcal/mol lower than that of the isolated H and H2. The intermolecular vibration frequency is smaller than 50cm L The height of the vibrational-adiabatic barrier is 9.4 kcal/mol, the H-H distance 0.82 A. The barrier was approximated by an Eckart potential with width 1.5-1.8 A. The rate constant has been calculated from eq. (2.1), using the barrier height as an adjustable parameter. This led to a value of Vq similar to that of the gas-phase reaction H -I- H2.  [c.113]
