Journal ArticleDOI
Preparation of dithioesters from alkynethiolates and thiols: Evidence for the intermediate occurrence of thioketenes
TL;DR: In this paper, a solution of lithium alkynethiolates, RCCSLi, to an excess of a thiol was used to obtain satisfactory yields by adding ethereal solutions.
Journal ArticleDOI
Isolation and crystal structure of a presumed intermediate in the reaction of an organolithium compound with an epoxide
Sjoerd Harder,Jaap Boersma,Lambert Brandsma,Jan A. Kanters,Albert J. M. Duisenberg,Joop H. van Lenthe +5 more
TL;DR: In this paper, a set of AML4 AM1 parameters for aluminum is presented, and the results from calculations using their values are generally closer to experimental than either MNDO or Stewart's newly introduced PM3.
Journal ArticleDOI
Efficient Procedures for the Cu(I)-Catalyzed Methoxylation of 2-and 3-Bromothiophene
TL;DR: Substitution of halogens in aromatic and heteroaromatic compounds by alkoxide or aryloxy groups is catalyzed by copper, and its salts as mentioned in this paper, and complete conversion requires prolonged heating at elevated temperatures.
Journal ArticleDOI
Control of the Reaction of n-Butyllithium with Benzo[b]tellurophene by the Solvent—Either Metalation or Tellurium–Lithium Exchange To Give an Interesting Lithiostyryllithium
Journal ArticleDOI
Synthesis and Ag+-catalyzed cyclization of 2,3-dienamides
Nina A. Nedolya,Nataly I. Schlyakhtina,Valentina P Zinov'eva,Alexander I. Albanov,Lambert Brandsma +4 more
TL;DR: In this article, the reaction of 1-lithiated methoxyallene and lithiated 3-methyl-1,2-butadiene with isocyanates, RNCO (R=alkyl) followed by hydrolysis affords the dienamides H 2 C(C(OCH 3 )C( O)NHR and CH 3 ) 2 C
