KHFe(CO)4 reacts with tris(amino)phosphines by substitution at phosphorus leading to [bis(amino)phosphine]tetracarbonyliron complexes [(R1R2N)2PH]Fe(CO)4. The X-ray structure has been determined for R1=R2=Ph. Deprotonation of these complexes with KH affords stable potassium phosphidotetracarbonylferrates which can be alkylated or acylated at phosphorus.

The cis effects of phosphine, arsine and stibine ligands have been evaluated by measuring the IR stretching frequency in dichloromethane of the carbonyl ligand in a series of Rh(I) Vaska-type complexes, trans-[RhCl(CO)(L) 2]. These data were correlated with those obtained by Tolman for the electronic trans influences in the [Ni(L)(CO)3] complexes. The electronic contribution, chiFc, of ferrocenyl was determined as 0. 8 from these plots by evaluating PPh2Fc as ligand. In order to accommodate arsine and stibine ligands an additional correction term, to compensate for differences in the donor atom, was added to Tolman’s equation for calculation of the Tolman electronic parameter of phosphine ligands. In the resulting equation: nu(CONi)=2056.1+?i=1 3chii+CL values for CL of C P=0, CAs=-1.5 and CSb=-3.1 are suggested for phosphine, arsine and stibine ligands, respectively. The crystal and molecular structures of trans-[RhCl(CO)(PPh2Fc)2]¡¤2C 6H6, trans-[RhCl(CO){P(NMe2)3} 2] and trans-[RhCl(CO)(AsPh3)2] are reported. The Tolman cone angles for PPh2Fc and P(NMe2)3 were determined as 169 and 166, while the effective cone angles for PPh2Fc, P(NMe2)3 and AsPh3 were determined as 171, 168 and 147, respectively.

Chemistry of Phosphorus Ylides: Part 46?Efficient Synthesis and Biological Evaluation of New Phosphorus, Sulfur, and Selenium Pyrazole Derivatives

1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazole-4-carbaldehyde was allowed to react with different phosphorus, sulfur, and selenium reagents. The reaction products depend on the nature of the reagent and the condition of the reaction used. Treatment of the carbaldehyde with the active phosphacumulene ylides afforded the phosphoranylidene pyranopyrazoles. On the other hand, its reaction with the stable phosphonium ylides gave the oxaphosphetanes. Sulfidodithiaphosphetane pyrazole was generated from the reaction of Japanese reagent with the carbaldehyde. Selenido-oxaselenaphosphetane and dioxaphospholane pyrazoles were obtained from the reaction of the carbaldehyde with Woolin’s reagent and phosphorus triamide, respectively. The antimicrobial screening of the synthesized compounds was also evaluated.
