Rare examples of P-C reductive elimination in ruthenium complexes to generate phosphonium salts are presented. Triarylphosphines are converted into benzophospholium or phosphaphenalenium ligands via cyclometalation and 1,2-insertion of an alkyne followed by P-C reductive elimination. The intermediate in each step was successfully characterized using NMR and X-ray diffraction studies.

We report the results of psychological evaluation of a floor wiper developed in accordance withWe report the results of psychological evaluation of a floor wiper developed in accordance with the consumer needs for gap cleaning of floors. Specifically, we examined the effect of cleaning floors the consumer needs for gap cleaning of floors. Specifically, we examined the effect of cleaning floors with this wiper on mood and usability in two experiments. Participants cleaned the floor of a dining-with this wiper on mood and usability in two experiments. Participants cleaned the floor of a dininglike environment, including gaps between the furniture. They used two different floor wipers under like environment, including gaps between the furniture. They used two different floor wipers under two conditions, a) an easy-wiper condition in which participants used a wiper that targeted the gaps, two conditions, a) an easy-wiper condition in which participants used a wiper that targeted the gaps, and b) a difficult-wiper condition in which participants used a wiper that occasionally got stuck in the and b) a difficult-wiper condition in which participants used a wiper that occasionally got stuck in the gaps. Mood ratings were taken before and after. After the cleaning, the usability of wiper was also gaps. Mood ratings were taken before and after. After the cleaning, the usability of wiper was also measured. The results showed that positive mood increased, and negative mood decreased under the measured. The results showed that positive mood increased, and negative mood decreased under the easy-wiper condition compared to the difficult-wiper condition after the cleaning task (Experiment 1) . easy-wiper condition compared to the difficult-wiper condition after the cleaning task (Experiment 1) . In Experiment 2, the positive/negative mood differences between the tool conditions were smaller in In Experiment 2, the positive/negative mood differences between the tool conditions were smaller in an environment with fewer obstacles. The usability was generally higher in the easy-wiper than in the an environment with fewer obstacles. The usability was generally higher in the easy-wiper than in the difficult-wiper conditions. The present study identified that floor cleaning with a wiper, compatible with difficult-wiper conditions. The present study identified that floor cleaning with a wiper, compatible with the floor-cleaning environment, improved the post-cleaning moods. These results could be derived from the floor-cleaning environment, improved the post-cleaning moods. These results could be derived from the processing fluency of haptic maneuvering of wipers. the processing fluency of haptic maneuvering of wipers.
