Efficient diastereoselective pinacol coupling reaction of aliphatic and aromatic aldehydes by using newly utilized low valent titanium bromide and iodide species
TL;DR: In this article, the coupling reaction of aromatic and aliphatic aldehydes was conducted under mild conditions to give the corresponding pinacols in moderate to high yields and dl -diastereoselectivities by using combinations of either low valent titanium(II) bromide and copper or titanium(IV) iodide and gold in a mixed solvent of dichloromethane and pivalonitrile.
Journal ArticleDOI
Reaction of C60 with Chlorophenyldiazirine. Spectral and Electronic Properties of the C60-Chlorophenylcarbene 1:1 Adduct
Koichi Komatsu,Akifumi Kagayama,Yasujiro Murata,Nobuyuki Sugita,Kaoru Kobayashi,Shigeru Nagase,Terence S.M. Wan +6 more
TL;DR: In this paper, a reaction of C60 with an equimolar amount of chlorophenyldiazirine in refluxing toluene afforded the C60-chlorophenylcarbene 1:1 adduct in 37% yield.
Journal ArticleDOI
Efficient method for pinacol coupling of aromatic and aliphatic ketones by using titanium(II) chloride and zinc in the presence of pivalonitrile
TL;DR: In this paper, the reductive coupling reaction of aromatic and aliphatic ketones including acyclic-aliphatic-ketones with titanium(II) chloride and zinc in the presence of pivalonitrile was investigated.
Journal ArticleDOI
A Novel Carbodication Composed of Two Tris(bicyclo[2.2.2]octeno)tropylium Units Connected by a Triple Bond: Synthesis, Structure, and Properties
TL;DR: The bis[tris(bicyclo[2.2]octeno)cycloheptatrienyl]acetylene dication 3 as mentioned in this paper, which is the first example of the acetylene having two tropylium ion units at both ends, has been synthesized by stepwise introduction of the tris[cyclo[ 2.2.
Journal ArticleDOI
Diastereoselective Aldol and Reformatsky Reactions of α-Halo Carbonyl Compounds and Aldehydes Mediated by Titanium(II) Chloride
TL;DR: In this article, aldol reactions of α-bromo ketones with several aldehydes were successfully carried out by using a combination of titanium(II) chloride and copper or sodium iodide in dichloromethane-pivalonitrile at low temperature.
