Embodiments in accordance with the present invention encompass compositions encompassing a latent organo-ruthenium compound and a pyridine compound along with one or more monomers which undergo ring open metathesis polymerization (ROMP) when said composition is exposed to suitable actinic radiation to form a substantially transparent film. Surprisingly, the compositions are very stable at ambient conditions to temperatures up to 80° C. for several days and undergo mass polymerization when subject only to actinic radiation. Accordingly, compositions of this invention are useful in various opto-electronic applications, including as 3D printing materials, coatings, encapsulants, fillers, leveling agents, among others.

A process produces a mono vinyl ether, R—O—CH═CH.sub.2. R represents an organic group with at least three carbon atoms. The process involves reacting a mono hydroxy compound. R—OH, with acetylene in presence of a catalyst to get a product mixture containing the mono vinyl ether, unconverted mono hydroxy compound, and the catalyst. To the product mixture, an ester is added that contains at least one ester group, X—O.sub.2C—. X is a hydrocarbon group containing less carbon atoms than R. The remaining mono hydroxy compound R—OH is reacted with the ester in the presence of the catalyst to get a transesterification product containing at least one ester group, R—O.sub.2C—, and an alcohol, X—OH. The mono vinyl ether is isolated from the product mixture obtained after the ester addition, optionally followed by purification of the mono vinyl ether by distillation.

[Problem]

An object of the present invention is to provide a compound suitable for a low refractive index layer in a capping layer in order to improve the light extraction efficiency of an organic EL device.

[Solution]

The present invention was achieved by focusing on the fact that an adamantane compound has excellent thin film stability and finding that an amide compound, an ester compound, an amine compound, or an ether compound, in which adamantane is arranged at the center, exhibits a low refractive index property, and an organic EL device having excellent luminous efficiency was obtained by using this compound as a material for forming a capping layer having a low refractive index.

Provided is a method with which an α-allylated cycloalkanone is obtained from a cyclic compound cycloalkanone used as a starting material. The method is a method for producing an α-allylated cycloalkanone represented by General Formula (III), and the method includes: a step 1: reacting a compound represented by General Formula (I) and alcohol having 1 or more and 4 or less of carbon atoms in the presence of a first acid catalyst and optionally a dehydrating agent; and a step 2: reacting a crude product obtained in the step 1 and a compound represented by General Formula (II) in the presence of a second acid catalyst to produce an α-allylated cycloalkanone represented by General Formula (III). The step 1 and the step 2 are consecutively performed. In the formulae above, the group -A.sup.1- (it should be noted that the front bond refers to a bond that binds to the carbon atom C.sup.1 and the back bond refers to a bond that binds to the carbon atom C.sup.2) is an alkylene group having 4 or more and 20 or less of carbon atoms that optionally contains a hetero atom and optionally has a substituent, and R.sup.4 is a hydrogen atom or an alkyl group having 1 or more and 4 or less of carbon atoms.
