Hydridic Rhenium Nitrosyl Complexes with Pincer-Type PNP Ligands
Bibliographic record
Abstract
The hydride complexes ReHBr(NO)[HN(C 2 H 4 PR 2 ) 2 ] (R = Pr i, 1a; Bu t, 1b ) were synthesized by reactions of [NEt 4 ] 2 [Re(NO)Br 5 ] with the pincer-type ligands HN(C 2 H 4 PR 2 ) 2 . Treatment of 1a and 1b with Bu t OK led to their dehydrobromination, resulting in the amido hydrides ReH(NO)[N(C 2 H 4 PR 2 ) 2 ] ( 2a, b ), respectively. The dihydride trans -ReH 2 (NO)[HN(C 2 H 4 PPr i 2 ) 2 ] ( 3a ) was obtained by stirring an ether solution of 2a under hydrogen. Similarly, partial conversion of 2b was achieved under hydrogen to give trans -ReH 2 (NO)[HN(C 2 H 4 PBu t 2 ) 2 ] ( 3b ). The structure and properties of complexes 1 − 3 were studied by DFT calculations. Complexes 2a and 3a demonstrated low activity for transfer hydrogenation of acetophenone and cyclohexanone due to instability in 2-propanol.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
