Csp3–P versus Csp2–P Bond Formation: Catalyst-Controlled Highly Regioselective Tandem Reaction of Ene-Yne-Ketones with H-Phosphonates
TL;DR: A copper carbene generation or a Michael addition is proposed as the key step in the selective construction of the Csp(3)-P or CSp(2)-P bond, which is supported by carbene capture reactions and interval (31)P NMR experiments.

Calcium carbide as the acetylide source: transition-metal-free synthesis of substituted pyrazoles via [1,5]-sigmatropic rearrangements
TL;DR: In this paper, a wide range of N-tosylhydrazones derived from aldehydes or ketones were used to synthesize pyrazoles in good yields with high regioselectivities.

One-Pot Synthesis of Spirocyclic or Fused Pyrazoles from Cyclic Ketones: Calcium Carbide as the Carbon Source in Ring Expansion.
TL;DR: N-Tosylhydrazones generated in situ from cyclic ketones smoothly underwent a [3 + 2] cycloaddition to afford saturated spirocyclic pyrazoles and further transformed to the fused analogues via a ring expansion in certain cases.

Facile synthesis of cyanofurans via Michael-addition/cyclization of ene–yne–ketones with trimethylsilyl cyanide
TL;DR: A Michael-addition/cyclization procedure between ene-yne-ketones and TMSCN under metal-free conditions is developed and a wide range of cyanofurans was delivered in high yields, which could be further transformed to a series of furo-furanimines,furo-pyridazines or carboxamido-furans.

Access to Polysubstituted (Furyl)methylthioethers via a Base-Promoted S-H Insertion Reaction of Conjugated Enynones.
TL;DR: A convenient and applicable approach to the construction of diverse functionalized (2-furyl)methylthioether derivatives via base-promoted S-H insertion of conjugated enynones with thiophenols or thiols has been developed.
