Tolley, Lewis C.,Fernández, Israel,Bezuidenhout, Daniela I.,Guisado-Barrios, Gregorio
, p. 516 - 523 (2021/02/09)
The catalytic activity of a set of mono- and bimetallic Rh(i) and Ir(i) complexes bearing carbene-linker-carbene (CXC) bis-triazolylidene ligands (with X = O, N) coordinated in a bridging or chelating fashion was evaluated in the hydrothiolation of alkyne

A series of novel cationic and neutral Rh complexes with an N-donor-functionalized 1,2,3-triazol-5-ylidene (TRZ) ligand (in which the pendant N donor is NHBoc, NH2, or NMe2) is described. The catalytic activity of these complexes was

Thurow, Samuel,Ostosi, Naiana T.,Mendes, Samuel R.,Jacob, Raquel G.,Lenard?o, Eder J.
experimental part, p. 2651 - 2653 (2012/06/30)
A very simple procedure is described for the efficient synthesis of vinyl sulfides by hydrothiolation of terminal alkynes using 1-n-butyl-3- methylimidazolium methylselenite, [bmim][SeO2(OCH3)]. The reaction proceeds cleanly under mi
Synthesis of vinyl sulfides using glycerol as a recyclable solvent
Lenardao, Eder J.,Silva, Marcio S.,Lara, Renata G.,Marczewski, Junior M.,Sachini, Maraisa,Jacob, Raquel G.,Alves, Diego,Perin, Gelson
experimental part, p. 272 - 282 (2011/05/13)
A new, clean, and efficient protocol is described for the hydrothiolation of terminal alkynes promoted by KF/Al2O3, using glycerol as recyclable solvent. This improved method furnishes selectively the corresponding anti-Markovnikov v
Synthesis of vinyl sulfides via hydrothiolation of alkynes using Al2O3/KF under solvent-free conditions
Silva, Márcio S.,Lara, Renata G.,Marczewski, Júnior M.,Jacob, Raquel G.,Lenard?o, Eder J.,Perin, Gelson
, p. 1927 - 1930 (2008/09/19)
We present here a clean, solvent-free hydrothiolation of alkynes using solid supported catalyst (Al2O3/KF). This efficient and improved method selectively furnishes the corresponding anti-Markovnikov vinyl sulfides in good to excellent yields. The method is applicable for aliphatic and aromatic thiols and the catalytic system can be re-used up to two times without previous treatment and with comparable activity.

This invention relates to compounds of the formula: STR1 wherein R is an electron withdrawing group; R1 is H or COZ; X1 and X2 are independently H, lower alkyl, aryl, aryl lower-alkyl or polystyrene or R and X1 taken together with the carbon atoms to which they are attached form a ring containing from 4 to 15 ring carbon atoms and may contain up to 2 heteroatoms, wherein the heteroatoms are O, S, or N; and Z is an amino acid residue, a peptide residue or a leaving group. The compounds of the present invention are adaptable as blocking or protecting groups for an amine composition useful in peptide synthesis. The present invention is also directed to a method of protecting an amino group of an organic molecule during a reaction which modifies a portion of the molecule other than the protected amino group.
