Synthesis of O,S-diethyl 2-(bromomethyl-13C)-2-methylthiomalonate, a model substrate for methylmalonyl-co a mutase reactions

✦ Synopsis

Abstract

O,S‐Diethyl methylthiomalonate was efficiently condensed with paraformaldehyde‐^13^C in the presence of sodium methoxide to give 2‐[^13^C]‐hydroxymethylated product, which was converted to 2‐[^13^C]‐bromomethyl product by treatment with triphenylphosphine and carbon tetrabromide.

Reaction of A 2 CO 3 (A = K, Rb) with Sn and Se in an H 2 O/CH 3 OH mixture at 115±130 °C affords the isotypic selenidostannates(IV) A 6 Sn 4 Se 11 ´x H 2 O (A = K, x = 8) 1 and 2 whose discrete [Sn 4 Se 11 ] 6± anions each contain two corner-bridged ditetrahedral [Sn 2 Se 6 ] 4± species. Similar re
