Phosphonium Salt Organocatalysis
Advanced Synthesis & Catalysis, 2009AbstractThe field of organocatalysis is growing rapidly and attracts an increasing number of research groups. Most organocatalysts can be classified as Lewis bases, Lewis acids, Brønsted acids and Brønsted bases. However, examples of Lewis acid organocatalysis under homogeneous conditions are comparatively rare.

Tris(2-methylphenyl)phosphonium tetrachloroborate
Acta Crystallographica Section C Crystal Structure Communications, 2000The title compound, C(21)H(22)P(+).BCl(4)(-), is the first structurally characterized example of the [HP(o-tolyl)(3)](+) cation, presented here with BCl(4)(-) as the counter-ion. The cation has a near-tetrahedral P atom and the BCl(4)(-) anion is near-tetrahedral at boron. There are no unusually short cation-anion contacts.

Tetrakis(diethylamino)phosphonium bromide hemihydrate
Acta Crystallographica Section C Crystal Structure Communications, 2000The structure of the title compound, C(16)H(40)N(4)P(+).Br(-).0. 5H(2)O or [P¿N(C(2)H(5))(2)¿(4)]Br.0.5H(2)O, at 130 K has Z' = 4 and is ionic, with Br not bonded to P. The P atoms are tetrahedral, with P-N distances in the range 1.628 (2)-1.6400 (19) A. The N atoms are approximately planar. The water molecules form cyclic hydrogen-bonded [(H(2)O)(2)Br(
