- ACIDIC HYBRID MONOMERS AND DENTAL MATERIALS BASED THEREON
-
Acidic monomer according to Formula I: in which A is a linear or branched aliphatic C1-C18-hydrocarbon group, which can be interrupted by one or more —O??, —S—, —CO—O—, —O—CO—NH—, —HN—CO—NH— or —CO—NR1—; R1 is H or a C1-C6 alkyl group; X is absent or is a linear or branched aliphatic C1-C10 hydrocarbon group, which can be interrupted by one or more —O—, —S—, —CO—O—, —O—CO—NH—, —HN—CO—NH— or —CO—NR2—; R2 is H or a C1-C6 alkyl group; PG is a radically polymerizable group, preferably vinyl, allyl, CH2═CR3—CO—Y— or R4O—CO—C(═CH2)—CH2—Y—; Y═O or NR5 or is absent; R3 is H or CH3; R4 is H or a C1-C7 alkyl group; R5 is H or a C1-C7 alkyl group; n is 1, 2, 3 or 4; m=1 or 2; p=1, 2 or 3; and q=1, 2 or 3. The monomers are particularly suitable as components of dental material.

- Access to macrocyclic endocyclic and exocyclic allylic alcohols by nickel-catalyzed reductive cyclization of ynals
-
Ni-catalyzed reductive macrocyclizations of ynals are reported. Disubstituted alkynes afford either endocyclic or exocyclic allylic alcohols depending on the ligand. Phosphine ligands favor the formation of endocyclic olefins, whereas N-heterocyclic carbe
