 Title    Spaltung der Ylid-Bindung in Phosphor-Yliden: Photolyse von thiophosphoranylsubstituierten (Triphenylphosphoranyliden)methanen Cleavage of Ylidic Bonds in Phosphorus Ylides: Photolysis of Thiophosphoranyl-Substituted (Triphenylphosphoranylidene)methanes  
 Abstract    The thiophosphoranyl-substituted (triphenylphosphoranylidene)methanes 1, 6 a, b are cleaved photolytically (/ > 300 nm, 3 d, 0 °C) to yield triphenylphosphane and the thio-aza-phosphetanes 3 and 8 a, b, b', respectively. The formation of these heterocycles is explained in­ voking insertion o f the carbenes 2 and 7 a, b into the methine CH bond of one of the isopropyl groups. If 6a is irradiated for 16 h in the presence of the phosphanes P(NM e2)3, P(OMe)3 or P("Bu)3, the new ylides 9 a, b, c are obtained along with small quantities of 8 a. These results indicate a cleavage of the ylidic bond in 1 and 6a, b. The failure of attempted cyclopropana-tion reactions of olefins as well as the absence of the expected product o f a 1,2-H shift, 10, in the case of the photolysis of 6b leave doubts as to the occurrence of free carbenes.

 Title    The Crystal Structure of IV ^SiNPPl^CF^PPl^ and NM R Investigations on its Proposed Thermal Isomerization  
 Abstract    The crystal structure of Me^SiNPPh-.CH-.PPh-, (1) has been determined in order to obtain information about the ground state conformation in the solid, and about unusual steric effects which could give rise to conformational isomers. It was recently proposed that such isomers exist due to restricted rotation about the P = N bond, and are generated by heating the com­ pound to 160 C. The evidence for them was based on the observation of multiple N M R sig­ nals in CDClj solutions of samples which had been so treated. The crystal structure yields a P -N -S i bond angle of 150.2(2) , a P -N bond length of 1.529(3) A and a S i-N bond lengths of 1.668(3) A. It is clear that, as a result of the relatively large P -N -S i angle in 1, there is no steric hindrance to rotation about the P -N bond in this molecule. Attempts to study the ener­ getics of the proposed isomerization by recording the N M R spectra of heated samples showed that the previously reported multiple N M R signals are not generated in this way. However, such signals are generated at ambient temperature under various circumstances, for example in the course of the reaction of a CDC13 solution of 1 with methanol to produce HNPPh-,CH2PPh2 (2). The observation that it is not necessary to heat 1 in order to generate these signals makes their assignment to rotational isomers rather less likely. In the absence of a reproducible method of producing these signals in a pure sample, the existence of such isomers should be regarded as not yet proven.

A 250 ps-vacuo-trajectory was calculated using the Molecular Dynamics program G R O M O S. Structural data and M D results are compared to N M R spectroscopic data. A Karplus-type relation was confirmed for coupling constants 3ypp.

 Title    Neue Carbodiphosphorane. Notiz zur Reaktion zwischen Bis(dimethylamino)fluormethylidenphosphoran und /i-Butyllithium New C arbodiphosphoranes. N ote on the Reaction between Bis(dimethylamino)fluoromethylidene-phosphorane and «-Butyllithium  
 Abstract    The main product from the reaction between bis(dimethylamino)fluoromethylidene-phos-phorane (1) and «-butyllithium in the presence of tetramethylethylenediamine is /j-butyl-di-methylamino-methyl-{[tris(dimethylamino)phosphoranylidene]methylene}-phosphorane (7). As a by-product from the reaction between methyl-bis(dimethylamino)difluorophosphorane and rt-butyllithium bis(dimethylamino)-methyl-{[«-butyl-bis(dimethylamino)phosphor-anylidene]methylene}-phosphorane (9) was isolated in small yield. The new carbodiphosphor­ anes 7 and 9 are characterized by their 'H , 13C, and 31P N M R and mass spectra.
