"AN ORGANOMAGNESIUM COMPOUND"

Abstract The present invention is related to an organomagnesium compound having the general formula wherein n is 1 or 2; R1 is a substituted or unsubstituted C4-C24 heteroaryl, containing one or more heteroatoms as B, O, N, S, Se, P, F, CI, Br, I, or Si; linear or branched, substituted or unsubstituted C1-C20 alkyl, C2-C20 or C2-C20 alkinyl; or substituted or unsubstituted C3-C20 cycloalkyl; or derivative thereof; X and Y are independently or both CI, Br or I, preferably CI; HalOn (Where n=3, 4); carboxylate of formula RCO2; alkoxide or phenoxide of formula RO; dialkoxide of formula LiO-R-O; disilazide of formula (R3Si)2N; thiolate of formula SR; RP(0)02; or SCOR; where R is defined as R1 above; linear or branched, substituted or unsubstituted C1-C20 alkyl or C3-C20 cycloalkyl amine of formula RNH; dialkyl/arylamine of formula R2N (where R is defined as above or R2N represents a heterocyclic alkylamine); phosphine of formula PR2 (where R is defined as above or PR2 represents a heterocyclic phosphine); OnSR (where n=2 or 3 and R is defined as above); or NOn (where n=2 or 3); or X = R1 as defined above; and a derivative thereof.

(Formula Removed)
wherein
n is 1 or 2;
R1 is a substituted or unsubstituted C4-C24 aryl or C3-C24 heteroaryl, containing one or
more heteroatoms as B, O, N, S, Se, P, F, CI, Br, I, or Si; linear or branched, substituted or
unsubstituted C1-C20 alkyl, C2-C20 alkenyl or C2-C20 alkinyl; or substituted or unsubstituted
C3-C20 cycloalkyl; or derivative thereof;
X and Y are independently or both CI, Br or I, preferably CI; HalOn (Where n=3, 4); carboxylate of formula RCO2; alkoxide or phenoxide of formula RO; dialkoxide of formula LiO-R-O; disilazide of formula (R3Si)2N; thiolate of formula SR; RP(O)O2; or SCOR; where R is defined as R1 above;
linear or branched, substituted or unsubstituted C1-C20 alkyl or C3-C20 cycloalkyl amine of formula RNH; dialkyl/arylamine of formula R2N (where R is defined as above or R2N represents a heterocyclic alkylamine); phosphine of formula PR2 (where R is defined as above or PR2 represents a heterocyclic phosphine); OnSR (where n=2 or 3 and R is defined as above); or NOn (where n=2 or 3); or X = R1 as defined above; and a derivative thereof.
2. The compound as claimed in claim 1, wherein the compound is (R1)2Mg-LiY
3. The compound as claimed in claim 1, wherein the compound comprises R1(MgX)n and LiY in a molar ratio of 0,05-6,0.
4. The compound as claimed in claim 1-3, wherein Y is CI, tert-butylate or sec-butylate.


5. The compound as claimed in one or more of claims 1 or 3, 4, which is i-PrMgCI-LiCI or
sec-BuMgCI-LiCI, in a molar ratio between i-PrMgCI or sec-BuMgCI and LiCI of 0,05 to 6,0.
6. The organomagnesium compound as claimed in claim 1, whenever used in the preparation of organometallic compounds and their reaction with electrophiles.
