Phosphanylhydrosilylalkynes R2HSiCCPAr2 (R,Ar: Me,4-tBuC6H4 1, Me,Mes 2, Mes,Ph 3; Mes = 2,4,6-Me3C6H2) were prepared and the reactions with B(C6F5)3/

A Ph2P(O)-protected alkyne underwent dephosphorylation by treatment with MeMgBr in THF with Me3Si-protection untouched. The dephosphorylation followed by a transition-metal-catalyzed coupling of the resulting terminal a lkyne with aryl halides was carried out in a one-pot manner to afford the desired coupling product. Selective deprotection of Me3Si-/Ph2P(O)-protected alkynes enabled facile syntheses of expanded π-systems such as cyclic phenyleneethyny lenes and unsymmetrically substituted ditriazol.

Diphenylphosphanylethyne (3a) reacts with tris(pentafluorophenyl)borane at room temperature by a typical frustrated Lewis pair (FLP) reaction. It undergoes a sequential series of 1,2-phosphane/borane additions to the alkyne unit in an overall 2:2 molar ra

A protecting group Ph(O) for terminal ethyne was newly developed. This protecting group can be introduced readily to terminal ethyne by CuI-catalyzed phosphination and subsequent oxidation with H Ph(O)-protected ethynes remained intact in Sonogashira coup
Copper-catalyzed anti-hydrophosphination reaction of 1-alkynylphosphines with diphenylphosphine providing (Z)-1,2-diphosphino-1-alkenes

Hydrophosphination of 1-alkynylphosphines with diphenylphosphine proceeds in an anti fashion under copper catalysis, providing an easy and efficient access to a variety of (Z)-1,2-diphosphino-1-alkenes and their sulfides. The reaction is highly chemoselec
