Lawrence, Nicholas J.,Beynek, Hayrettin
, p. 497 - 498 (2007/10/03)
The Wittig olefination of substituted aromatic aldehydes with ylides from phosphorinanium salts [RCH2P(Ph)(CH2)5]+Br- in which the phosphorus atom is incorporated into a six-membered ring, is E-selective.
Crystal Strucutres of Some Cyclic Phosphonium Salts and Their Relation to the Stereochemical Course
Gallucci, Judith C.,Holmes, Robert R.
, p. 4379 - 4386 (2007/10/02)
Single-crystal X-ray analyses of 1-benzyl-1-phenylphosphorinanium bromide (I) and 1,1-diphenyl-4-methylphosphorinanium bromide (II) showed that their structures are very similar.Each contains the six-membered ring in the chair form and in the case of I th
