A novel synthetic route to a 9-phosphatriptycene was developed by utilizing ortho-lithiation of a triarylphosphine oxide as a key step. Systematic comparisons of the NMR spectra of 9-phosphatriptycene derivatives indicated the large s character of the lone pair orbital or the phosphorus-chalcogen bonds of the 9-phosphatriptycene derivatives.

They have been characterized by spectroscopic methods. The molecular structure of [3·(HOAc)(H2O)] has been determined crystallographically. The complexes [3·(HOAc)2], [Rh2(mu-OAc)3{mu-(C6H 3-4-OMe)P(C6H4-4-OMe)2}(HOAc) 2] ([4·(HOAc)2]), and [Rh2(mu-OAc)2{mu-(C6H 3-4-OMe)P(C6H4-4-OMe)2} 2(HOAc)2] ([5·(HOAc)2]) reversibly react with CO giving mono- and biadducts.

A new approach was developed for Pd(II)-catalyzed aromatic coupling of oxabenzonorbornadienes with triarylphosphines as both ligands and aryl donors. Diverse functional groups including halo- (F-, Cl-, and Br-), CF3-, and furyl groups are well tolerated. For unsymmetrical triarylphosphines, the migration ability of aryls is consistent with the electronic property of substituents and maintains the order EDG-Ar > H-Ar > EWD-Ar (EDG means electron-donating group, EWG means electron-withdrawing group). A preliminary mechanistic study was also disclosed.

A stepwise procedure allowing the formation of symmetrical arylphosphines is described. It relies on the use of preformed functionalized aromatic organozinc reagents to perform arylations of chlorophosphines. Some preliminary results concerning the synthesis of unsymmetrical diarylphenylphosphines through sequential coupling of organozinc species with dichlorophenylphosphine are also reported.

Two new low bandgap conjugated polymers, PBDTS-ID and PBDTS-DTNT, containing isoindigo (ID) and naphtho[1,2-c:5,6-c’]bis[1,2,5]thiadiazole (NT), respectively, as an electron-deficient unit and alkylthiothienyl-substituted benzodithiophene (BDTS) as an electron-rich unit, were designed and synthesized by palladium-catalyzed Stille polycondensation. Both polymers showed good thermal stability up to 330 C and broad absorption ranging from 300 to 842 nm. Electrochemical measurement revealed that PBDTS-ID and PBDTS-DTNT exhibited relatively low-lying highest occupied molecular orbital energy levels at -5.40 and -5.24 eV, respectively. These features might be beneficial for obtaining reasonable high open-circuit voltage and high short-circuit current. Polymer solar cells (PSCs) were fabricated with an inverted structure of indium-tin oxide/poly(ethylenimine ethoxylate)/polymer:PC71BM/MoO3/Ag. As a preliminary result, the PSCs based on PBDTS-ID and PBDTS-DTNT exhibited moderate power conversion efficiencies of 2.70% and 2.71%, respectively.

A synthetic method for the efficient construction of beta-hydroxylactones and lactams bearing alpha-quaternary carbon centers is described. This transformation relies on an electronically differentiated Lewis base catalyst, which is uniquely capable of promoting a reductive aldol reaction of alpha,alpha-disubstituted and alpha,alpha,beta-trisubstituted enones. This approach provides a valuable synthetic alternative for carbon-carbon bond formation in complex molecular settings due to its orthogonal reactivity compared to that of traditional aldol reactions. Based on this method described herein, lactones, lactams, and morpholine amides bearing alpha-quaternary carbon centers are accessible in yields up to 85% and 50:1 dr.

A systematic study of the reaction between the dinuclear complex [{Rh(mu-Cl)(eta4-COD)}2], (COD = 1,5-cyclooctadiene) with 14 different triarylphosphines is presented. When two equivalents of the phosphine are employed, the main product is the mononuclear complex [RhCl(eta4-COD)(PR3)], with R = 4-(OCH3)C6H4 (1), 4-(CH3)C6H4 (2), C6H5 (3), 4-FC6H4 (4), 4-(CF3)C6H4 (5), 4-ClC6H4 (6), 3-(OCH3)C6H4 (7), 3-(CH3)C6H4 (8), 3-ClC6H4 (9), 2-(OCH3)C6H4 (10), 2-(CH3)C6H4 (11) and R3 = (C6H5)2(C6F5) (12). No mononuclear complex could be isolated with the electron poor phosphines P(C6H5)(C6F5)2 and P(C6F5)3. A chemical equilibrium in solution was observed between the dinuclear and mononuclear species, with the formation of the mononuclear being disfavoured by the use of bulky and electron poor phosphines. The mononuclear complex 11, with the extremely bulky phosphine P(2-CH3C6H5)3, was undetected in solution by NMR, however could be crystallized and its molecular structure determined by X-ray diffraction and compared with the previously reported structures for 3 and 4. For complexes with isosteric phosphines (1-6), an inverse relationship between the coupling constant 1JRh-P and the electronic parameter (chi) of the phosphine was observed.

An NCN pincer palladium complex was developed as a probe molecule to index the coordination ability of various monodentate ligands. Coordination constants of 27 monodentate ligands (L) with a pincer palladium complex to form complexes of the type ArPd(L)2Cl were determined by 1H NMR spectroscopy. This allowed the coordination ability of a wide variety of ligands, including P-coordinating ligands (phosphane, phosphite), as well as As-coordinating AsPh3, and N-coordinating pyridine, to be indexed. The differential between the highest/lowest coordination constants was 10 12. The relative coordination ability is described in a logarithmic manner, log(Keq(L)/Keq(PPh3)), with respect to the value of PPh3 to exhibit high linearity in the Hammett plot.
