Isolable Phosphanylidene Phosphorane with a Sterically Accessible Two-Coordinate Phosphorus Atom**

Phosphanylidene-s-phosphoranes (RP=PR’3) are phosphorus analogues of alkylidene-s-phosphoranes (R2C=PR’3), better known as Wittig reagents. Phosphanylidene-s-phosphoranes are synthetically accessible in the free form (RP= PR’3) and also in the transition-metal-stabilized form (LnM !P(R)=PR’3). [1] The latter complexes are commonly used in both P=C bond generation and as a source of the phosphin...

Sterically encumbered tin and phosphorus peri-substituted acenaphthenes.

A group of sterically encumbered peri-substituted acenaphthenes have been prepared, containing tin moieties at the 5,6-positions in 1-3 ([Acenap(SnR3)2], Acenap = acenaphthene-5,6-diyl; R3 = Ph3 (1), Me3 (2); [(Acenap)2(SnMe2)2] (3)) and phosphorus functional groups at the proximal peri-positions in 4 and 5 ([Acenap(PR2)(P(i)Pr2)] R2 = Ph2 (4), Ph((i)Pr) (5)). Bis(stannane) structures 1-3 are d...

Sterically-constrained tripodal phosphorus-bridged tris-pyridyl ligands.

Introducing substituents into the 6-position of the 2-pyridyl rings of neutral tris-pyridyl phosphanes of the type P(2-py')3 (where 2-py' is a substituted 2-pyridyl ring), has a marked impact on their coordination of transition metal ions, as revealed in the current study. Whereas the unsubstituted phosphorus-bridged tris-pyridyl ligand P(2-py)3 (1) forms the sandwich cation [{P(py)3}2Fe](2+) (...

Accessible heavier s-block dihydropyridines: structural elucidation and reactivity of isolable molecular hydride sources.

The straightforward metathesis of 1-lithio-2-tbutyl-1,2-dihydropyridine using metal tert-butoxide (Na/K) has resulted in the first preparation and isolation of a series of heavier alkali metal dihydropyridines. By employing donors, TMEDA, PMDETA and THF, five new metallodihydropyridine compounds were isolated and fully characterised. Three distinct structural motifs have been observed; a dimer,...

Single Atom and Two Atom Ramsey Interferometry with Quantized Fields

Implications of field quantization on Ramsey interferometry are discussed and general conditions for the occurrence of interference are obtained. Interferences do not occur if the fields in two Ramsey zones have precise number of photons. However in this case it is shown how an analog of Hanbury-Brown Twiss photon-photon correlation interferometry can be used to discern a variety of interferenc...
