An easily operated bisulfite-free method was presented to detect and quantify 5fC through quantitative real-time PCR. Malononitrile can selectively label 5fC under mild reaction conditions causing a C-to-T conversion that affects the nick ligation of the complementary pairing oligos, and then the ligation product is amplified and visualized by qPCR.

Multisubstituted guanidines have received much attention because of important applications in many fields, such as pharmaceutics, organometallic and coordination chemistry, and organic synthesis. Although classical methods are available for the preparation of guanidines, synthetic preparation approaches to guanidines are still in great demand. In this review, we summarize recent developments on synthetic methods via the C-N bond formation. Three aspects are included: transition-metal-catalyzed guanidine synthesis based on classical methods; catalytic guanylation reaction of amines with carbodiimides; and tandem catalytic guanylation/cyclization reactions.

A new perovskite-like compound [N(CH3)4][Cd(N3)3] is reported here, which undergoes a series of reversible phase transitions including an above-room-temperature ferroelastic phase transition. An order-disorder mechanism is found in these structural transitions owing to the sway of the rod-like N3- bridges as well as the rotation of the tetrahedron-like [N(CH3)4]+ guests.

Mediated by AlCl3, substituted spiro[4.5]deca-tetraenes underwent novel and selective skeletal rearrangement to generate indene derivatives in high to excellent yields. [ABSTRACT FROM AUTHOR]

Selective cleavage of both active and inert C-C bonds in substituted allylcyclopropanes was realized via a novel ligand-controlled approach using zirconocene(II)-1-butene or zirconocene(II)-benzyne complexes. [ABSTRACT FROM AUTHOR]

Two new three-dimensional manganese(II) coordination polymers were assembled by 1,2,3-triazole-4,5-dicarboxylate, showing unusual multi-step magnetization jumps at 1.8 K due to the competing interactions between the antiferromagnetic couplings with different amplitudes. [ABSTRACT FROM AUTHOR]

The isolated cyclopentadiene moiety in a fullerene multi-adduct derivative reacts readily with dienophiles to form [4 + 2] cycloaddition products. [ABSTRACT FROM AUTHOR]

An unprecedented release of the bridging aqua molecules and conversion of chain helicity within a 3-D chiral cadmium(ii) dicarboxylate coordination polymer was observed in a unique and drastic single-crystal-to-single-crystal transformation of dehydration. [ABSTRACT FROM AUTHOR]

Mediated by CuCl, 1,4-dilithio-1,3-dienes reacted with carbon monoxide (CO) to generate multi-substituted cyclopentadienones and/or their head-to-head dimers, via tandem CO insertion and intra/intermolecular cycloaddition of organocopper compounds. [ABSTRACT FROM AUTHOR]
