Reactions of [(Me 3 Si) 2 N] 3 RE(μ-Cl)Li(THF) 3 with aminomethylene-substituted pyridine 2- Pr(2c), Nd(2d), Sm(2e), Dy(2f), Er(2g), and Lu (2h)). However, reaction of [(Me 3 Si) 2 N] 3 Y(μ-Cl)Li(THF) 3 with pyridin-2-ylmethyl-substituted amines such as 2-(RNHCH 2 )C 5 H 4 N (R = t Bu (3a) and 2,6-i Pr 2 Ph (3b)) or benzyl-substituted amine O(CH 2 CH 2 ) 2 NCH 2 CH 2 NHCH 2 C 6 H 5 (5) afforded the corresponding yttrium complexes containing monoanionic ligands [2-(RNCH 2 )C 5 H 4 N] 2 YN(SiMe 3 ) 2 (R = t Bu (4a) and 2,6-i Pr 2 Ph (4b 6). Dianionic α-iminopyridine rare-earth metal amido complexes showed high catalytic activities for the dehydrogenation coupling reaction of hydrosilanes and amines providing a variety of silylamines in high yields.

We investigated 16 Japanese spotted fever cases that occurred in southeastern China during September–October 2015. Patients had fever, rash, eschar, and lymphadenopathy. We confirmed 9 diagnoses and obtained 2 isolates with high identity to Rickettsia japonica strain YH. R. japonica infection should be considered for febrile patients in China.
