Manganese is a cheap and environmentally friendly metal on Earth. Herein, we report a manganese-promoted reductive cross-coupling using easily available and odorless disulfides as thiolating agents in an excellent 100% sulfur atom economy. The protocol featured a broad substrate scope, including various alkyl disulfides and excellent functional group compatibility, constructing diverse thioethers under
A radiation polymerisable composition comprising: (A) a donor/acceptor component for forming a charge transfer complex said component being selected from the group consisting of: (iii) a bifunctional compound having an electron donor group and an electron withdrawing group and a polymerisable unsaturated group; (iv) a mixture of (a) at least one unsaturated compound having an electron donor group and a polymerisable unsaturated moiety; and (b) at least one unsaturated compound having an electron acceptor group and a polymerisable unsaturated group; and (B) a binder polymer composition.
