    Abstract: A compound of formula (I) wherein R1 is hydrogen or an organic radical of 1 to 100 carbon atoms, R2, R3 are independently hydrogen or an organic radical of 1 to 100 carbons, Z is a single bond or a divalent organic group of 1 to 100 carbons, A is an (n+m)-valent organic group of 1 to 1 000 000 carbons, X is a single bond or a divalent organic group of 1 to 40 carbons, n is an integer from 1 to 1000, m is 0, 1, or 2, the sum of n+m being an integer from 2 to 1002. Such compounds are obtainable from specific 4-oxy-but-2-yn-1-ol derivatives, or used as intermediate(s), crosslinker(s), or monomer(s) in polymerization or oligomerization reactions, or for two-component compositions having such compound(s) and multifunctional hardener(s). Such compound(s) may be used to prepare polyunsaturated compounds, by reaction with an (oligo/poly)-functional nucleophile, or polymers.

    Abstract: A process for preparing an isocyanate compound is provided. The process includes a step of reacting an amine compound A having at least one primary amino group with CO2 and an organotin compound S having at least one radical OR3 attached to the tin atom of the organotin compound to convert at least one of the primary amino groups in the amine compound A into a carbamate group to obtain a carbamate compound C; a step of cleaving the carbamate groups in the obtained carbamate compound C to form the isocyanate compound and an alcohol R3OH, without separation of the tin compounds; and a step of obtaining the isocyanate compound. The radical R3 is a C-bound organic radical of 1-30 carbon atoms with 1, 2, or 3 carbon atoms optionally replaced by oxygen or nitrogen.

    Abstract: Process for preparing branched alcohols of the general formula (I) where the groups R1 are different or identical and selected from C2-C3-alkyl, linear or branched, using at least one alcohol of the formula (II) R1—CH2—CH2—OH  (II) in homogeneous phase in the presence of at least one base, wherein at least one Ru(II)-containing complex compound is used in which the Ru(II) has at least one ligand L1 which is at least bidentate, where at least one coordination site of L1 is a nitrogen atom.

    Abstract translation: 制备通式（I）的支链醇的方法，其中基团R1不同或相同且选自直链或支链的C 2 -C 3 - 烷基，使用至少一种式（II）的醇R 1 -CH 2 -CH 2 - OH（II）在至少一个碱的存在下在均相中，其中使用至少一种含Ru（II）的络合物，其中Ru（II）具有至少一个至少二齿配位体L1，其中 L1的至少一个配位部位是氮原子。
