An improved synthesis of the strong base P(MeNCH2CH2)3N

Jiansheng Tang; John G. Verkade

Abstract The proazaphosphatrane P(MeNCH 2 CH 2 ) 3 N is synthesized in high yield from (HMeNCH 2 CH 2 ) 3 N and ClP(NEt 2 ) 2 . The last compound is synthesized from inexpensive PCl 3 and HNEt 2 .


Phosphorus Sulfur and Silicon and The Related Elements | 1994

Chemical Games with Molecular Footballs, Darts and Paddlewheels

Jiri Pinkas; Jiansheng Tang; Yanjian Wan; John G. Verkade

Molecules of the title types take part in a wide variety of chemical and structural games. Some of the more surprising transformations are discussed and rationales for them are put forth.
