TBPB-promoted metal-free synthesis of thiophosphinate/phosphonothioate by direct P-S bond coupling

An efficient method for the direct coupling of thiol/thiophenol with H-phosphine oxides or H-phosphinate esters is reported. Without using any metallic catalyst, the direct sulfur-phosphorus bond coupling reaction was promoted using tert-butyl peroxybenzoate in the presence of KI at room temperature. Consequently, thiophosphinate/phosphonothioate was produced in moderate to excellent yields.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.78871-05-3, Name is Di(naphthalen-2-yl)phosphine oxide, molecular formula is C20H15OP. In a Article£¬once mentioned of 78871-05-3, Computed Properties of C20H15OP

A t-BuONa-mediated C-OH/P(O)-H cross dehydration coupling to produce alkylphosphine oxides is developed. This reaction employed readily available alcohols and P(O)-H compounds as the starting materials, providing an efficient alternative method for constructing sp3 C-P bonds. A reasonable reaction path involving dehydration and subsequent regio-selective hydrophosphorylation of the resulting alkenes was proposed.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of C20H15OP, you can also check out more blogs about78871-05-3

Metal- and oxidant-free S-P(O) bond construction: Via direct coupling of P(O)H with sulfinic acids

We have developed a simple and convenient method for S-P(O) bond formation between R2P(O)H and sulfinic acids under metal-, oxidant-, and halogen-free conditions. The current method is compatible with a broad range of substituents on various substrates including halogens and heterocyclic moieties.
