Thioamides and Thioformamides for Sequential Reactions with Organolithium and Grignard Reagents |
|
Toshiaki Murai and Yuichiro Mutoh |
| [Full Text PDF(J-STAGE)] |
 |
| Sequential reactions of thioamides and thioformamides with organolithium and Grignard reagents are described. Thioiminium salts derived from these sulfur isologues of amides readily react with lithium acetylides to lead to several types of products, including α,β-unsaturated ketones, whereas sequential additions of lithium acetylides and Grignard reagents afford propargylamines. The direct addition of organolithium and Grignard reagents to thioformamides proceeds with high efficiency to give a range of tertiary amines. |

A Revisit to Molecular Orbitals in H2+, LiH, HF, and Hybridization |
|
Shin-ichi Nagaoka, Hiroyuki Teramae, and Umpei Nagashima |
| [Full Text PDF(J-STAGE)] |
 |
| We have drawn three-dimensional contour plots of H2+ molecular orbitals and carbon hybrid orbitals according to explanations given in quantum chemistry textbooks and have also performed ab initio molecular orbital calculations of LiH and HF. Some contour representations and molecular orbital energy level diagrams thus obtained are not consistent with the figures adopted in the textbooks. It is considered that the usual explanations for the molecular orbitals of H2+, LiH, HF, and hybridization in the conventional textbooks are liable to misunderstanding. |
