The titled 2,1-benzazaphosphole (1) (i. e. ArP, where Ar=2-(DippN=CH)C6 H4 , Dipp=2,6-iPr2 C6 H3 ) showed a spectacular reactivity behaving both as a reactive heterodiene in hetero-Diels-Alder (DA) reactions or as a hidden phosphinidene in the coordination toward selected transition metals (TMs). Thus, 1 reacts with electron-deficient alkynes RC≡CR (R=CO2 Me, C5 F4 N) giving 1-phospha-1,4-dihydro-iminonaphthalenes 2 and 3, that undergo hydrogen migration producing 1-phosphanaphthalenes 4 and 5. Compound 1 is also able to activate the C=C double bond in selected N-alkyl/aryl-maleimides RN(C(O)CH)2 (R=Me, tBu, Ph) resulting in the addition products 7-9 with bridged bicyclic [2.2.1] structures. The binding of the maleimides to 1 is semi-reversible upon heating. By contrast, when 1 was treated with selected TM complexes, it serves as a 4e donor bridging two TMs thus producing complexes [μ-ArP(AuCl)2 ] (10), [(μ-ArP)4 Ag4 ][X]4 (X=BF4 (11), OTf (12)) and [μ-ArP(Co2 (CO)6 )] (13). The structure and electron distribution of the starting material 1 as well as of other compounds were also studied from the theoretical point of view.Despite the growing literature on loneliness, little attention has been paid to the impact of broader changes in social structure and environment on individuals' experience of loneliness. Drawing on data from the 2018 Urbanization and Quality of Life Survey (N = 3,229) conducted in 40 localities undergoing rural-urban transition in China, this study investigates how measures of urbanisation (including population density, duration of urban status, neighbourhood transition and housing type) are associated with residents' loneliness. We revised measures of the six-item De Jong Gierveld Loneliness Scale, differentiated between emotional and social loneliness, estimated multi-level mixed-effects regressions and controlled for a number of individual-level covariates. The results show that emotional loneliness and social loneliness have different patterns of association with multi-level covariates urbanisation at county, township and neighbourhood levels is significantly associated with emotional loneliness, whereas residence in temporary housing is a clear risk factor for social loneliness. The analyses further demonstrate that the revised measures of loneliness address concerns about the original scale, offer a clearer sense of the degrees of loneliness and are strongly associated with multi-level covariates and psychological distress. In addition to showing how urbanisation leads to greater individual loneliness, our research also illustrates how to model locational parameters in analyses of individual well-being.The purpose of this study was to investigate the effect of sodium butyrate on slaughter performance, serum indexes and the intestinal barrier in rabbits. Six hundred healthy weaned rabbits were randomly divided into three groups (5 replicates per group, 40 rabbits per replicate) control (fed a basal diet), sodium butyrate (fed a basal diet containing 0.5% sodium butyrate) and antibiotic (fed a basal diet containing 0.004% antibiotic). The trial lasted 35 days, including 7 days of pretesting and 28 days of formal testing. The results showed that dietary sodium butyrate supplementation increased the full-bore weight, the half-bore weight and the half-bore rate of rabbits. Meanwhile, the content of aspartate aminotransferase (AST) in serum was increased in rabbits fed the sodium butyrate diet. According to the intestinal barrier, after adding sodium butyrate to feed, the tight junction function of the rabbit intestine is enhanced, and the intestinal microbial composition is also improved. To sum up, after sodium butyrate was added to feed instead of antibiotics, slaughter performance was significantly enhanced, serum indexes were improved, and intestinal barrier function was also enhanced. GSK484 Therefore, sodium butyrate can be added to feed as an additive and can replace antibiotics. Monitoring
