The present invention provides a process for producing fluorine-containing alkene represented by Formula (2): Rf1C(Rf2)═CH2 wherein Rf1 and Rf2 are the same or different, and are F, H, F(CF2)n- wherein n is an integer of 1 to 5, or H(CF2)m- wherein m is an integer...
which is 3,3 dmethylbutanol. We could think of forming an alkene from 3,3 dmethylbutanol by performing another E2 elimination (or dehydration) to remove the alcohol and anti-periplanar proton which would form 3,3-dimethylbutene. In the forward reaction, we...
Our new diisocyanates are preferably prepared by the reaction of certain diamines with an excess of phosgene in an inert solvent. The diamines employed have the idealized, general structural formula: R'--Z--R"--CH2 NH2 where R', R", Z, R1 and R2 have the meanings set forth above and...
Diamines suitable for use in the preparation of the polyamides include straight chain and branched, alkyl, aryl and alkylaryl diamines. Such diamines include, for example, those represented by the general formula H2 N(CH2)n NH2, I wherein n is an integer of from 2 to 16, such as trim...
(since the term doesn’t differentiate them based on the total number of double bonds in their chemical structures). general formula of olefins the general formula of an acyclic olefin that contains one double bond (alkene) is c n h 2n . this implies that there are twice as many hydrogen...
According to the present invention, there is added to the polyester-polycarbonate blend an amount effective to inhibit ester-carbonate interchange of at least one substituted carboxylic acid derivative having the above formula. The X1value therein may be either 0 (preferably) or NH. The X2value ...
Optoelectronic devices include polysiloxanes derived from hydrosilation of an organometallic compound of formula L2MZ, wherein L and Z are independently bidentate ligands
X is an alkyl, cycloalkyl, or aromatic radical or a radical of the formula ##STR5## R1 is a divalent aliphatic, alicyclic, heterocyclic or unsubstituted or substituted aromatic hydrocarbon radical. 7. A polymer composition made by reacting a mixture comprising: about 5 to about 95 weight...
