2-(Dimethoxymethyl)benzyl alcohol: a convenient isobenzofuran precursor. Smith, James G.; Dibble, Peter W. (Guelph-Waterloo Cent. Grad.Chemicals with cas numbers 3029-32-1 and 26580-83-6 also play role. Work Chem., Univ. Waterloo, Waterloo, ON N2L 3G1, Can.). J. Org. Chem., 48(26), 5361-2 (English) 1983. CODEN: JOCEAH. ISSN: 0022-3263. DOCUMENT TYPE: Journal CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) Section cross-reference(s): 25 A convenient synthesis of compds. useful for the in situ generation of isobenzofuran is described. The synthesis begins with 2-HO2CC6H4CHO and leads to the isobenzofuran precursors 2-(HOCH2)C6H4CH(OMe)2 (I) and 1-alkoxyphthalans. The use of I as a source of isobenzofuran is illustrated by reactions with p-benzoquinone, 1,4-naphthoquinone, di-Me fumarate, and maleic anhydride. .

DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) Section cross-reference(s): 75, 76 This study explores the assembly in the cryst. state of a class of pentacenes that are substituted along their long edges with arom. rings forming rigid, cruciform mols. The crystals were grown from the gas phase, and their structures were compared with DFT-optimized geometries. Both crystallog. and computed structures show that a planar acene core is the exception rather than the rule. In the assembly of these mols., the Ph groups block the herringbone motif and further guide the arrangement of the acene core into higher order structures. The packing for the phenyl-substituted derivs. is dictated by close contacts between the C-H's of the pendant arom. rings and the carbons at the fusions in the acene backbone. Using thiophene substituents instead of phenyls creates cofacially stacked acenes. In thin films, the thiophene-substituted deriv. forms devices with good elec. properties: relatively high mobility, high ON/OFF ratios, and low threshold voltage for device activation. An unusual result is obtained for the decaphenyl pentacene when devices are fabricated on its cryst. surface. Although its acene cores are well isolated from each other, this material still exhibits good elec. There are some commonly used reagents like 3029-32-1 in this article. properties. ..
