The synthesis of 30 new triorganosilyl and triorganostannyl esters of orthoboric, metaboric, and arylboronic acids are described: (R3SiO)3B {R3=nBuMe2, PhMe2, [2-(3-cyclohexenyl)ethyl]Me2, (nOctadecyl)Me2, nHex3}; (R3MO)3B3O3 {M=Si: R3=nPr3, nBu3, nHex3, EtMe2, nBuMe2, [2-(3-cyclohexenyl)ethyl]Me2, [(Me2HC)(Me)2C]Me2, (nOctadecyl)Me2, PhMe2, Ph2Me, Ph3. M=Sn, R=Ph, Me}; (R3MO)2BAr {M=Si: Ar=Ph, R3=nPr3, nBu3, Ph2Me; Ar=C6H4Br-4, R=Ph, nPr; Ar=C6H4Me-2, R=Ph, nPr. M=Sn: R=Ph, Ar=Ph, C6H4Br-4… CONTINUE READING
