    • Methylene dithiepane silanes according to Formula I in which R1 is a saturated or unsaturated aliphatic or alicyclic hydrocarbon radical with 1 to 10 carbon atoms, which can be interrupted by one or more oxygen and/or sulphur atoms and can contain one or more ester, carbonyl, amide and/or urethane groups, or is an aromatic or heteroaromatic hydrocarbon radical with 6 to 18 carbon atoms, the hydrocarbon radicals being able to be substituted or unsubstituted; R2 has one of the meanings given for R1 or is absent; R3 has one of the meanings given for R1 or is absent; R4 is equal to —(CHR6)n—, —Y—CO—NH—(CHR6)n—, —Y—CO—NH—R5—, —(CHR6)n—S—R5—, —S—R5—, —CO—O—R5— or is absent, with n being equal to 1 to 4, R6 is hydrogen, C1 to C10 alkyl or C6 to C10 aryl, R5 has one of the meanings given for R1 and Y stands for an O or S atom or is absent; with R5 and R6 being able to be substituted or unsubstituted; X is a hydrolyzable group; a, b, c and x each independently of each other being 1, 2 or 3; and the sum of a+x=2 to 4. The silanes are particularly suitable for the preparation of dental materials.
