标 题:Methods for the synthesis of di(hydroxymethyl)tetrahydrofuran and its application in polyesters and polyurethanes
发明人：SPIEGELBERG BRIAN; BRANDT ADRIAN; BECK HORST; KUX ALEXANDER; TIN SERGEY; DE VRIES JOHANNES GERARDUS
权利人:HENKEL AG & CO KGAA
摘要:The present invention relates to the synthesis of di(hydroxymethyl)tetrahydrofuran (DHMTHF) and the preparation of trans-enriched mixtures of DHMTHF. The invention further refers to polyester polyols which are obtained by reaction of cis/trans DHMTHF mixtures with a dicarboxylic acid. The invention further relates to polyurethanes and compositions containing a polyester polyol comprising DHMTHF, in particular to such polyurethane-containing (adhesive) compositions.

标题 :Process for the synthesis of azobenzene compounds having a cyano group in one or both of the ortho positions of the diazo component radical
发明人：BUECHELER PAUL
权利人:SANDOZ LTD
摘要:A process for the synthesis of an azobenzene compound having a cyano group in one or both of the ortho positions of the diazo component radical comprising reacting the corresponding azobenzene compound having a chloro, bromo or iodo substituent in one or both of the ortho positions of the diazo component radical with a copper thiocyanate or copper thiocyanate-forming mixture of salts in the presence of an oxidizing agent (e.g., oxygen and sodium perborate), whereby the or at least one of the chloro, bromo and iodo substituents is replaced by a cyano group.

标题 :Convergent synthesis of multiporphyrin light-harvesting rods
发明人：LINDSEY JONATHAN S; LOEWE ROBERT S
权利人:UNIV NORTH CAROLINA STATE
摘要:The present invention provides a convergent method for the synthesis of light harvesting rods. The rods are oligomers of the formula A 1 (A b+1 ) b , wherein b is at least 1, A 1 through A b+1 are covalently coupled rod segments, and each rod segment A 1 through A 1+b comprises a compound of the formula X 1 (X m+1 ) m wherein m is at least 1 and X 1 through X m+1 are covalently coupled porphyrinic macrocycles. Light harvesting arrays and solar cells containing such light harvesting rods are also described, along with intermediates useful in such methods and rods produced by such methods.
