Regioselective One-Pot Synthesis of Triptycenes via Triple-Cycloadditions of Arynes to Ynolates

We developed the novel one-pot synthetic method of substituted triptycenes by the reaction of ynolates and arynes. This four-step process involves three cycloadditions and electrocyclic ring opening of the strained Dewar anthracene. Each of the three related but structurally distinct classes of nucleophiles (ynolate, enolate, and anthracenolate) reacts with o-benzyne in the same predictable manner controlled by chelation and negative hyperconjugation. The resulting functionalized C3-symmetrical triptycenes hold promise in the design of functional materials.

Process for preparing polycyclic dyes

Described herein is a process for preparing a polycyclic dye which comprises reacting a compound of the Formula (2): STR1 with a compound of the formula: STR2 wherein X and X1 are, for example, hydrogen or halogen, X2 and X3 are halogen and Z is --CN, --CO2 R or --CONR1 R2 where R, R1 and R2 are, for example, alkyl. Processes for making compounds of Formulas (3) and (4) are also disclosed.

TRIBUTYLSTIBINE MEDIATED SYNTHESIS OF 1,1,2-TRI-SUBSTITUTED CYCLOPROPANES

A novel method for the synthesis of 1,1,2-tri-substituted cyclopropanes is reported which involves the reaction of electron-deficient olefins with dibromomalonic ester, dibromocyanoacetic or dibromobenzeneacetic ester promoted by tri-n-butylstibine.The reaction was carried out under mild conditions to give the cyclopropane derivatives in moderate to good yields.Other R3M (M= As,Sb,Bi) reagents as promoter for this reaction have been studied and seem to be less effective than tributylstibine.
