Transition-Metal-Free Synthesis of Borylated Thiophenes via Formal Thioboration
Bel Abed, Hassen,Blum, Suzanne A.
, p. 6673 - 6677 (2018/10/24)
A simple, regiocontrolled, and transition-metal-free approach to access exclusively 3-borylated thiophene derivatives is reported. The commercially available B-chlorocatecholborane reagent (ClBcat) acts as a carbophilic Lewis acid to activate the alkyne i
Synthesis of 3-iodothiophenes via iodocyclization of (Z)-thiobutenynes
Santana, Amanda S.,Carvalho, Diego B.,Cassemiro, Nadla S.,Viana, Luiz H.,Hurtado, Gabriela R.,Amaral, Marcos S.,Kassab, Najla M.,Guerrero Jr., Palimécio G.,Barbosa, Sandro L.,Dabdoub, Miguel J.,Baroni, Adriano C.M.
supporting information, p. 52 - 55 (2014/01/06)
A simple synthesis of 3-iodothiophenes was demonstrated using a wide range of (Z)-thioenynes. The key step in the iodocyclofunctionalization was the selective reduction of the triple bond in (Z)-thioenynes by the addition of iodine as an electrophilic age
Improvement in the synthesis of (Z)-organylthioenynes via hydrothiolation of buta-1,3-diynes: A comparative study using NaOH or TBAOH as base
Santana, Amanda S.,Carvalho, Diego B.,Casemiro, Nadla S.,Hurtado, Gabriela R.,Viana, Luiz H.,Kassab, Nájla M.,Barbosa, Sandro L.,Marques, Francisco A.,Guerrero Jr., Palimécio G.,Baroni, Adriano C.M.

Hydrothiolation of symmetrical and unsymmetrical buta-1,3-diynes with sodium organylthiolate anions in reflux, generated in situ by reacting C 4H9SH with NaOH, afforded (Z)-organylthioenynes in low to good yields (25-80%). By using tetrabutylammonium hydroxide (TBAOH) as base instead of NaOH, the hydrothiolation of buta-1,3-diynes was more rapid and efficient, providing (Z)-organylthioenynes in good to excellent yields (70-95%).
